switching loss of reverse MOSFET

Hi,

I am simulating an inverter model with your SiC MOSFET Plecs Model (C3M0021120K) and realize that there is only switching loss of forward MOSFET canal since when current is negative, all values are 0 (shown in the picture). So can I assume that in terms of the physical structure of MOSFET with Bodydiode inside, there are only turn-on on, turn-off switching losses of forward MOSFET and recovery loss of Bodydiode, not switching losses of reverse MOSFET, right?

Thanks a lot for your answer.

    Hi Joy,

    You are correct. I'd also like to add that at this time explicit modeling of the body diode reverse recovery loss isn't captured but it will be in a future update.

    Thanks,

    Zack
