Free Power Supply Design Tool
Free Power Supply Design Tool
This free power supply design tool 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.
  • 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.
  • 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.
  • Design Verification Test (DVT) report and more.
  • A tool for engineers: choose a circuit topology, put in your power supply specifications and click. A complete design is ready. Optimize the design automatically or manually to produce the best product performance.
  • A tool for managers: fast response to RFQs, more control on product cost and better product quality control. Surprise your customers by the speed and details of your proposals with the help of ready to use reports from PowerEsim.
  • A tool for component Vendors: promote your components directly to product design engineers through PowerEsim. No more application notes needed. No more delay due to design mistakes.
  • A tool for Trainees: students and trainees learn quickly through PowerEsim. Simulated waveforms and analysis give real life demonstration. How to start? Go to and get started. It is a free on-line tool.
  • Component loss analysis.
  • Essential waveforms.
  • Transformer winding design.
