Voltage dips in the network (lights flickering, other equipment slowing down)

Excessive heat and mechanical stress on the motor windings

Higher risk of tripping breakers or damaging the power supply

A three-phase motor starting reactor acts like a cushion – it temporarily reduces the current flow, allowing the motor to start gently. Once the motor reaches around 80–90% of its speed, the reactor is bypassed, and the motor runs at full voltage.

Applications – Motors That Commonly Use Starting Reactors

Three-phase motor starting reactors are used with large three-phase induction motors and synchronous motors in:

Pumps – Water treatment plants, oil refineries, and irrigation.

Fans & Blowers – Cooling towers, ventilation systems, and industrial air handling.

Compressors – Refrigeration, air compression, and process plants.

Cranes & Hoists – Port cranes, gantry cranes, and heavy lifts.

Marine Propulsion – Ship thrusters and propulsion motors.

Mining Equipment – Crushers, mills, and conveyor drives.

Typical kVA Range

Motor starting reactors can range from 15 kVA for smaller industrial motors to 2,000+ kVA for large plants, marine systems, and heavy industries.

Benefits of Using Three-Phase Reactors for Motors

Reduced Current Surge – Protects motors and wiring.

Due to their efficiency, size, and adaptability, switch mode power supplies (SMPS) have transformed contemporary electronics. Controlling Electromagnetic Interference (EMI), however, remains a constant issue in SMPS design. Even the most efficient SMPS can cause performance degradation, regulatory non-compliance, and functional failures in nearby electronics if EMI is not properly controlled. This blog delves into the function of EMI filtering in SMPS systems, discusses optimal design strategies, and provides actionable advice for producing cleaner, more dependable power supplies.

Understanding EMI in SMPS

Unwanted electrical noise or interference that a device produces or receives, resulting in performance problems either internally or in nearby systems, is referred to as EMI. Because of their high-frequency switching behaviour, SMPS devices are a major cause of EMI. The two main categories of electromagnetic interference (EMI) in SMPS are radiated EMI and conducted EMI. Noise from conducted EMI affects other devices connected to the same network by traveling through power lines. In contrast, radiated EMI is the emission of noise through electromagnetic radiation, which has an impact on neighbouring circuits and systems. Regardless of the sort of electromagnetic interference, it must be properly filtered.

Sources of EMI in SMPS

A fundamental understanding of the causes of EMI is necessary to develop efficient filters. The magnetic fields produced by magnetic components like transformers and inductors, as well as the harmonics produced by quick on-off switching transitions, all contribute to EMI. Furthermore, a bad PCB design, such as inadequate grounding, lengthy traces, and unshielded loops, may greatly increase EMI. Parasitic capacitance and inductance, which are frequently unavoidable at high frequencies, also serve as latent sources of EMI.

The role of EMI Filters in SMPS

The main goals of an EMI filter are to reduce the EMI produced inside the SMPS before it may exit the device and to shield the SMPS from external noise sources entering the power line. The SMPS is protected from external interferences and meets emission requirements because to this dual-action strategy.

Components of EMI filters

SMPS designs usually have the following common EMI filters:

· Common mode chokes, which reduce common-mode noise, which is noise that occurs equally on both lines in relation to the ground

· Differential mode chokes, which focus on differential noise, that is the noise between two conductors

· X-capacitors, which reduce differential mode noise across input lines

· Y-capacitors, which reduce common-mode noise between the input lines and ground

· Metal Oxide Varistors, which are occasionally paired with EMI filters to offer surge protection.

Each component of the noise spectrum has a specific role to play in controlling distinct aspects.

Best practices for EMI filter design in SMPS

· Understand noise profiles early

Describe the noise prior to beginning filter design. Measure both common-mode and differential-mode noise across a range of frequencies. As a result, the filter design is targeted and efficient.

· Improve the layout of the printed circuit board

Layout errors are the source of many EMI problems. It’s crucial to shorten critical traces, particularly those carrying high di/dt currents, and to separate high-power and low-power areas of the board in order to reduce EMI. The widespread usage of ground planes helps to minimize noise by providing a low-impedance return route. For adequate EMI management, it is also necessary to reduce parasitic inductance by positioning decoupling capacitors next to switching devices.

· Employ adequate shielding

In some cases, simply optimizing the PCB is insufficient. Use ferrite materials or grounded metal enclosures to shield vulnerable locations.

· Choose the appropriate chokes

Differential-mode chokes work well for low-frequency differential noise, whereas common-mode chokes are necessary for reducing high-frequency common-mode noise. Selecting the appropriate core material is essential; ferrite cores are ideal for high-frequency applications, while powdered iron cores are more effective at lower frequencies.

· Balance the x and y capacitors

Differential-mode noise should be filtered using X-capacitors, but they should be safety-rated as Class X1 or X2. Y-capacitors, which filter common-mode noise, should also be safety-rated (Class Y1 or Y2) and used sparingly to reduce leakage current, which is particularly important in medical and portable applications.

· Include surge protection at the beginning

Line surges may be mitigated by Transient Voltage Suppression (TVS) diodes or metal oxide varistors (MOVs), which safeguard the filter and any downstream circuits, preserving the integrity of the filter and the dependability of the SMPS.

· Isolate sensitive components

Where possible, use physical separation or internal filtering to isolate noisy areas (such as the switching nodes) from delicate analog circuits.

Common mistakes in EMI filtering

There are a few typical errors that can impair the efficacy and system stability of EMI filters for SMPSs. Some of the major dangers to be aware of are as follows:

· Over-filtering: Over-filtering can result in instability, especially when interacting with feedback loops.

· Poor placement of filter components: The power entry point must be located next to the filters.

· Neglecting differential and common-mode noise balance: Concentrating on just one sort of noise, whether differential or common-mode, results in insufficient EMI management.

· Assuming consistent filter performance across all loads: Under no-load, full-load, and transient circumstances, EMI performance must be evaluated.

Testing EMI performance

Thorough testing is necessary to guarantee adherence to EMI laws. The main testing techniques and instruments include:

· When conducting emission testing, use a Line Impedance Stabilization Network (LISN).

· Check for both common-mode and differential-mode conducted noise up to 30 MHz (or more for certain standards).

· Radiated emissions usually require an open area test site (OATS) or an anechoic chamber.

· Early development stages involve pre-compliance testing, which helps identify problems before expensive certifications.

Managing EMI in SMPS systems is a combination of art and science. Engineers can assure high-performance, compliant, and reliable power supplies by understanding the sources of EMI, carefully designing PCB layouts, selecting the appropriate filtering components, and validating through rigorous testing. With the continued progress of power electronics, particularly with novel materials like GaN and SiC, maintaining a lead with smart EMI filtering techniques will be essential for success.

Working with reputable manufacturers is essential for high-quality EMI filtering solutions. For instance, Miracle Electronics is a recognized SMPS transformer manufacturer in India that provides a variety of EMI filters and components made for challenging SMPS applications. Their products guarantee outstanding noise reduction, regulatory adherence, and long-term reliability in a variety of industries like aerospace, medicine, and industry.

Be sure to accurately calculate your lighting load and distribute wattage evenly if you are using multiple voltage taps. Only plug the transformer into the outdoor GFCI outlet once all connections are securely made.

Common installation mistakes to avoid

Even top-quality equipment can fail to perform optimally if not installed correctly. Here are some common pitfalls to avoid when considering landscape lights with transformer:

· Overloading the transformer

Each transformer has a specified maximum wattage limit. To prevent overheating and allow for future upgrades, never exceed 80% of its capacity. Surpassing this limit can result in short circuits or complete transformer failure.

· Using the wrong wire gauge

Low-voltage lighting systems are particularly sensitive to wire gauge. Utilizing wire that is too thin can increase resistance and lower voltage, causing your lights to be dim or inoperative. Always determine the necessary gauge based on the distance and total wattage.

· Incorrect tap selection

Multitap transformers provide various voltage outputs to counteract voltage drops over extended wire lengths. Selecting the wrong tap (for instance, using 12V for a 150-foot run) can lead to dim or inconsistent lighting. Ensure you choose the appropriate voltage tap based on the distance of the fixture from the transformer.

· Inadequate weather protection

Although most landscape transformers are designed to withstand weather conditions, it is crucial to shield them from standing water, extreme temperatures, and direct exposure to rain and snow. Consider using protective covers or placing the transformer in a sheltered location when needed.

Maintenance of landscape lighting transformers

Regular maintenance is essential for keeping your landscape lighting system both efficient and safe over time. Here are some important tips for maintaining your transformer:

· Check the connections regularly

Vibrations and changes in weather can cause wire connections to become loose over time. Open the transformer panel and examine all terminal screws to ensure they are tightly secured. Also, inspect the wire insulation for any signs of damage, corrosion, or exposure.

· Clean the vents and housing from time to time

Transformers typically have ventilation slots designed to prevent overheating. Ensure these slots are clear of dust, spider webs, or any debris that could obstruct airflow. Occasionally, wipe down the exterior of the transformer with a damp cloth.

· Observe performance

If you notice dim, flickering, or non-working lights, it may indicate voltage irregularities or transformer wear. Regularly measure the voltage at the fixtures to identify any potential issues early on.

Troubleshooting common issues

Even with careful installation and upkeep, you may still face occasional issues. Here’s a guide to help you identify and resolve the most frequent problems:

· Lights not turning on

First, verify that the transformer is securely plugged in and that the GFCI outlet is operational. To test the system, bypass the timer or photocell to see if it activates manually. If your transformer has built-in circuit breakers, check them and reset if needed. Additionally, examine all wiring connections at the terminal block to ensure they are secure and undamaged.

· Dim or uneven illumination

This issue is often caused by a voltage drop, particularly when fixtures are located far from the transformer. To address this, consider using a higher voltage tap, such as 14V or 15V. Furthermore, using a wire gauge that is too small can lead to dim lighting; opting for thicker gauge wires is advisable for longer distances. Make sure to verify your total wattage; if it surpasses the transformer’s capacity, consider upgrading to a model with a higher capacity.

· Flickering lights

Flickering lights are usually the result of loose connections at either the transformer or the fixtures. Ensure all wire connections are tightened and check for any irregularities in the power supply. If flickering continues, test or replace any faulty photocells.

· Transformer overheating

If the transformer is overheating, it may be overloaded. To remedy this, reduce the total wattage or add another transformer to distribute the load. Ensure that vents are clear of debris to allow for proper airflow. Finally, confirm that the unit is installed in a well-ventilated area and not exposed to direct sunlight.

Why choosing the right transformer matters

Your transformer serves as the core component of your landscape lighting system. Opting for a high-quality, multitap transformer enables you to adjust the voltage output according to the distance of the fixtures, which helps mitigate voltage drop and enhances overall performance.

LED lighting has transformed contemporary illumination through its energy efficiency, extended lifespan, and enhanced brightness control. Nonetheless, a prevalent issue that impacts both LED performance and user comfort is LED flicker, which refers to the rapid variations in light output that may or may not be perceptible to the human eye. Flickering LEDs can lead to eye strain, headaches, and general discomfort, making it a critical concern in settings such as photography studios, smart homes, hospitals, and industrial environments. One of the most effective methods to mitigate LED flicker is by utilizing programmable power supplies, which offer stable power regulation, advanced dimming features, and increased efficiency. In this blog, we will examine the causes of LED flicker, its effects on users, and the essential role of programmable power supplies in reducing flicker for enhanced visual comfort and performance.

What is LED flicker?

LED flicker is characterized by the rapid and repeated variations in light output caused by inconsistencies in the electrical current supplied to the LED. While some flicker can be seen by the human eye, high-frequency flicker may go unnoticed yet still result in discomfort and long-term effects. LED flickers can be categorized as visible or invisible. A visible flicker occurs when the light output fluctuations are slow enough to be detected (typically below 100 Hz), which can be distracting and uncomfortable. In contrast, invisible flicker refers to high-frequency flicker (above 100 Hz) that is not easily perceived but can still contribute to eye strain, fatigue, and neurological issues with prolonged exposure.

What causes LED flicker?

Multiple factors lead to LED flicker, primarily stemming from inconsistencies in power supply and limitations of drivers. The following are some prevalent causes:

· Inconsistent power supply and voltage variations: LEDs necessitate a stable and regulated current for optimal performance. When the power supply experiences voltage fluctuations, the light output from the LED will also fluctuate, resulting in noticeable flickering.

· Inferior quality LED drivers: Numerous LED fixtures depend on internal drivers to manage power. Drivers of subpar quality often struggle to maintain steady current levels, which can result in flickering problems.

· Pulse-width modulation (PWM) dimming challenges: PWM is a widely used dimming method that rapidly turns the LED on and off to decrease brightness. If the PWM frequency is insufficiently high, flickering may be perceived by the human eye, particularly at lower brightness settings.

· Electrical interference and ripple current: Ripple current arises during the AC-to-DC conversion process in power supplies. Excessive ripple can lead to unstable current flow to the LEDs, causing undesirable variations in brightness.

Effects of LED flicker on human health & performance

Even if LED flicker is not immediately apparent, extended exposure can adversely affect both health and productivity. Rapid fluctuations in light intensity compel the eyes to exert more effort, resulting in discomfort, dryness, and strain, particularly in environments illuminated by artificial lighting. For sensitive individuals, flickering light can provoke headaches and migraines, especially in settings with prolonged exposure to LEDs. Research indicates that working under flickering lights can diminish focus and cognitive performance, making sustained concentration more challenging. In professional contexts, flicker can lead to undesirable artifacts and inconsistent exposure in photography and videography, hinder medical diagnostics and microscopy in healthcare facilities, and cause motion blur and misperception in industrial environments, thereby increasing workplace risks. Considering these concerns, we will examine how programmable power supplies can effectively eliminate flicker and enhance lighting stability.

How programmable power supplies minimize LED flicker

A programmable power supply offers precise control over voltage and current, ensuring a consistent and flicker-free power source for LED lighting. In contrast to conventional fixed power supplies, it dynamically adjusts output voltage and current to prevent fluctuations that lead to flicker. Furthermore, it facilitates advanced dimming control by employing high-frequency modulation rather than low-frequency PWM dimming, which is often responsible for flicker. By operating at elevated frequencies, programmable power supplies reduce ripple current and electromagnetic interference, providing a stable power supply for LEDs. Additionally, some advanced models incorporate intelligent feedback mechanisms that continuously monitor LED performance and adjust power output in real time to account for variations, further minimizing flicker.

Applications where flicker-free LED lighting is crucial

A comprehensive understanding of transformer losses and strategies for their reduction is vital for enhancing both efficiency and reliability.

Types of transformer losses

Iron losses

Iron losses in a transformer’s core arise from alternating magnetic fields and are influenced by the core material, frequency, and flux density. These losses are primarily divided into two types: hysteresis loss and eddy current loss. Hysteresis loss occurs due to the continuous magnetization and demagnetization of the core material, resulting in energy being dissipated as heat during each cycle. The magnitude of hysteresis loss is determined by the area of the material’s hysteresis loop, with larger areas signifying greater energy loss. Conversely, eddy current loss is generated by circulating currents that are induced within the core as a result of the fluctuating magnetic field, which leads to resistive heating and additional energy loss.

· Minimizing strategies: To minimize these losses, several strategies can be employed. Hysteresis loss can be reduced by utilizing high-quality silicon steel cores that exhibit smaller hysteresis loop areas, adopting amorphous core materials with lower coercivity, and ensuring that transformers operate near their rated voltage to avoid excessive magnetization. Eddy current loss can be mitigated by implementing laminated cores that interrupt the paths of eddy currents, choosing core materials with higher electrical resistivity, such as cold-rolled grain-oriented (CRGO) silicon steel, and reducing the operating frequency when possible. The application of these strategies contributes to improved transformer efficiency and decreased energy loss.

Copper losses

Copper losses, referred to as I²R losses, arise in the windings of transformers as a result of the resistance inherent in the copper conductors. The magnitude of these losses is contingent upon the square of the current flowing through the conductors and the resistance of the winding material.

· Minimization strategies: To mitigate these losses, several strategies can be employed: utilizing conductors with low resistance, such as high-purity copper or aluminum, can be effective. Furthermore, optimizing the design of the windings to decrease resistance and improve cooling efficiency is crucial. Increasing the cross-sectional area of the conductors also contributes to a reduction in resistance. Additionally, maintaining adequate ventilation and cooling is essential for sustaining optimal operating temperatures, which in turn minimizes energy losses.

Stray losses

Stray losses are generated as a result of leakage flux, which induces eddy currents within the structural components of the transformer, such as the tank and core clamps.

· Minimization strategies: To reduce leakage flux losses, the implementation of magnetic shields can effectively contain stray flux. Additionally, optimizing the design of the core and winding geometry can further diminish flux leakage, thereby enhancing the efficiency and performance of the transformer.

Dielectric losses

Dielectric losses occur within the insulation of the transformer due to alternating voltage stresses. Although these losses are typically minimal, they may increase as the insulation ages.

· Minimization strategies: To mitigate insulation losses, it is advisable to utilize high-quality insulating materials and to perform regular testing and maintenance of the insulation. This approach ensures dependable transformer performance and minimizes the likelihood of failures.

Methods to improve transformer efficiency

To enhance performance and reduce losses, the following strategies should be adopted:

· Utilizing high-efficiency core materials: Innovative core materials, such as amorphous metals, exhibit significantly lower hysteresis and eddy current losses in comparison to conventional CRGO steel.

· Enhancing cooling methods: Effective cooling is essential to prevent excessive temperature increases, which can elevate resistance and losses. Cooling strategies may include the use of cooling fins and radiators in oil-immersed transformers for heat dissipation, as well as forced air cooling in dry-type transformers for effective thermal management.

· Optimizing load management: Transformers should function within their ideal load parameters to minimize losses. Overloading can lead to increased copper losses, while underloading results in suboptimal efficiency.

· Conducting regular maintenance and testing: Routine evaluations are crucial for identifying and rectifying potential inefficiencies. Important maintenance activities include oil analysis to ensure insulation integrity, thermal imaging to locate overheating areas, and resistance and insulation testing to evaluate the condition of windings and cores.
