    Monte Carlo Analysis for IC and Shunt Regulator are now available. Flyback output diodes' waveform are now open to public.
    Input Harmonic Module

    Input Harmonic module is a tool that can provide the waveform of input voltage and input current for the current power supply. One special feature of this tool is that it can simulate input harmonic without a power supply. By clicking "select circuit" button at the bottom, user can select different circuit modules for input harmonic simulation.
    Available circuit modules:
  • Bridge
  • Voltage Doubler
  • Bridge + PFC

  • User can adjust each component value for input harmonic simulation.
