Eoss loss consideration in hard switching

raghava235

Hai,

I have a query on Eoss consideration for switching loss. My application is on basic 2-level SPWM inverter design. I want to calculate the switching loss during hard switching. For that, is adding Eon, Eoff from the datasheet sufficient? Otherwise, it is adding Eon, Eoff, and Eoss from the datasheet. I was told that Eon and Eoff will have the Eoss inclusive, and just adding Eon and Eoff is sufficient. Is this true for hard switching? for soft ZVS Eoss won't be there so no need for Eoss addition. What is the case in Hard switching. Thank you.
