Apr.2025

A feature has been added to the DC-DC converter's flyback circuit, allowing the transformer parameters to be set arbitrarily.

Dec.2024

Three topologies (Flyback, Half-Bridge, Full-Bridge) have been added to the DC-DC converter for the second stage of AC-DC converter.

Online Circuit Simulator

The Online Circuit Simulator allows users to verify and select MOSFETs.
Operation is easily verified without the hassle of building a simulation environment and downloading element models.
By changing the MOSFET and circuit constants and comparing the simulation result waveforms and power conversion efficiency, you can identify the MOSFET that matches the target specifications.

  

Login is required to use the circuit simulator.
