In the world of electronics design and circuit simulation, many engineers focus on expensive commercial tools while overlooking highly capable free alternatives. LTspice has quietly established itself as one of the most powerful and reliable circuit simulation tools available, widely used for analog and power electronics analysis.

In 2026, LTspice is widely used for:

• Analog and mixed-signal circuit simulation • Power electronics and switching converter design • Waveform and transient analysis • Semiconductor and component modeling • Fast prototyping of electronic circuits

LTspice is known for its high-speed simulation engine, stability, and accuracy in modeling real-world circuit behavior. It allows engineers to test complex designs, analyze performance under different conditions, and validate circuits before moving to hardware implementation.

Its lightweight nature and strong simulation capabilities make it especially valuable for students, researchers, and professional engineers working in power systems, embedded electronics, and analog design.

Despite being free, LTspice delivers performance comparable to many premium simulation tools, making it a hidden gem in the electronics engineering ecosystem.

As circuit complexity continues to increase in modern electronics, tools like LTspice are proving that powerful engineering solutions do not always come with a high price tag.

Modern circuit design is not defined by cost — it is defined by capability, accuracy, and innovation.

Nous allons voir dans cet article une méthode de résolution de circuits qui s’appelle la méthode des tensions de noeud (ou méthode des potentiels de noeud). C’est une méthode que j’enseigne à l’Université en cours d’électrotechnique et j’ai eu envie de vous partager cela ici. La stratégie est simple : on identifie d’abord les noeuds du circuit (je rappelle qu’en électronique un noeud est un…

Saat ini saya kembali mempergunakan OS GNU/Linux di laptop. Sebelunya selang beberapa lama saya pernah mempergunakan dengan dual boot. Jejak tinkering-nya sebagian saya catatkan di sini: http://tinker.sunupradana.info/ dan di sini: https://elda.sunupradana.info/ .

Karena bidang pekerjaan saya, salah satu yang perlu ikut saya pertimbangkan adalah mengenai kompatibilitas antara software yang dipergunakan dengan OS. Sejak dahulu LTspice sudah bisa bekerja dengan baik di GNU/Linux. Baik karena pengembangnya melakukan desain yang baik, maupun WINE (https://www.winehq.org/) yang semakin lengkap. Yang perlu dicoba adalah software yang lain, karena bahkan aplikasi yang sebelumnya bisa berfungsi lancar di versi yang baru belum tentu akan sama baiknya.

Berikut adalah beberapa software yang sejauh ini dapat berfungsi baik di GNU/Linux Mint 20.2, baik secara native maupun dengan bantuan WINE. Sampai hari ini semua software yang diperlukan untuk kuliah Elektonika Daya, bisa dipakai degan baik.
