Hello all,

In my 3 phase simulation(screen shot attached) I can see different values of conduction loss in mosfet for positive and negative cycle(in one line cycle).

I have used Gansystems model for mosfets and used probe to get the conduction losses.

My line cycle is of 50 hz.

Am I missing a concept here? or the negative value of current results in lower value of conduction losses?
