    I am trying to develop an over current detector to sense the current in the source of a Sic Mosfet in a half bridge inverter using a PCB constructed Rogowski coil. Can anyone tell me how simulate a Rogowski current transfomer?

    Hi John,

    I’ve not used a rogowski coil before. For a 1st principles approach you can use our magnetic elements library to construct a “transformer” the trick will be to assign the proper inductance factor for the core. The formula on the wikipedia page for a coil is easily implemented in PSIM.

    This can be implemented with our magentic circuit elements or using a simple inductor and measuring the voltage across it.

    I hope this helps.
