What is PowerEsim?
A Switching Power Converter Design Platform on the Internet

Our Mission

"A tool for designing better power supply."
Dr. Franki N. K. Poon
Founder of PowerEsim

A New CAD tool on the Internet for Switching Power Supplies

PowerEsim- Free on-line switch mode power supply SMPS, circuit and transformer design, calculation, simulation software. More than 100 circuits and topologies are available with real constructed transformer.

It provides a virtual laboratory environment for users to wind and place every single turn of a transformer, and with the help of tens of thousands real modeled component on the market, user can simple pick and place the real component and stuff into the circuit, within a fraction of a second, our server will immediately return the result to the user. It is even faster than user turn off, replace a component and turn on a prototype in real environment, and more than that is no worry of getting explosion of the prototype on real bench.

We call this Result Oriented Design Approach, and without the necessity of expert knowledge, it can yield very high quality design in a very short time. While expertise can always use it to optimize a more efficiency solution or lower costs design with the same performance. It turns the pre-design phase from days to minutes and a very good verification tool for the final design.

In real laboratory, engineers can feel the heat, measure the stress, wind real transformer or wait and see how long the unit getting burned. With our seamless integration of different tool, e.g. thermal, MTBF, Life, DVT, Waveform, etc., user can do the same things in powerEsim virtual environment.
