Auto Transformers: Compact Efficiency for Voltage Control
When efficient voltage regulation and cost-effectiveness are priorities, Auto Transformers stand out as a smart solution. Unlike traditional transformers, auto transformers use a single winding for both primary and secondary sides, reducing size, weight, and material costs while delivering reliable voltage transformation for a variety of applications.
What is an Auto Transformer?
An Auto Transformer is a type of electrical transformer where part of the winding is common to both the primary and secondary circuits. This design allows for voltage adjustment with less copper and iron material, making it more compact and efficient for specific voltage ranges.
The auto transformer has a single continuous winding with taps at different points.
The input voltage is applied across a portion of the winding (primary side).
The output voltage is taken from another tap on the same winding (secondary side).
By varying the tap points, the transformer either steps voltage up or down efficiently with reduced losses.
