Estimate mosfet switching loss
WebNov 18, 2024 · jurij. 251 7 15. 1. You can probably plot the instantaneous power p ( t) = i D ( t) × v D S ( t) and you will see the peaks showing the turn-on and off losses with the conduction loss in the middle. If you average p ( t) along a switching cycle, you'll get the average power. Not sure switching losses are relevant in simulation as many stray ...
