Hi all, I am trying to simulate a bidirectional half bridge with MOSFETs. I have a thermal model for the losses, however depending on the duty cycle the current across one of the switches is always negative (using PLECS…

Hello, I am using PLECS to simulate the losses in an AC/DC inverter. During an 50Hz sine output period, the inverter is partially soft switching and a part hard switching dependent on the current ripple through the out…
