PowerEsim is free SMPS power supply design, manufacturer & product database/list, switching converter topologies, circuit analysis, magnetic design software, transformer/inductor simulation & calculation software, DVT, Differential mode EMI simulation, EMI measurement, Harmonics, Thermal, MTBF, Life time and Monte Carlo analysis tool. It support LED driver design, PFC, notebook adaptor, phone charger, DVD, TV, PC, ballast, dc-dc, ac-dc, dc-ac converter etc.

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 of real modeled components on the market, users can simply pick and place the real components into the circuit, and within a fraction of a second our server will immediately return the result to the user. It is even faster than modifying prototypes in a real environment, and furthermore the risk of getting explosions of the prototype on real bench is no longer a concern. It is Better than real.

Their Mission:

“A tool for designing better power supply.”
