I want to simulate a simple DC-DC boost converter based on a SiC power module 1697-CAB500M17HM3-ND. This item is modeled for Thermal analysis in PLECS, but the switching losses for the upper switch is zero (the lower side MOSFET’s switching losses are simulated correctly). I think, It comes from the negative side of the current and this negative current does not model for this SiC power MOSFETs (CAB500M17HM3).
On the other way, the upper side MOSFET’s current is reverse/negative and the SiC molded just modeled for the positive sides from (-10A to 1000A). Therefore, the PLECS shows the switching losses equal to zero which is wrong. How can I fix this error?
(For the conduction losses, it seems ok, as both negative and positive currents are modeled)
