Question

uestion 8 10 pts The IGBT used in a forward converter is rated 350-V and 20-A and its saturation collector-emitter voltage VcE is specified as 0.43-V What is the conduction loss when this element operates at 0.48 duty cycle?

Answer 1

Conduction loss = On state voltage drop x working current x duty cycle = 0.43 x 20 x 0.48 = 4.128 W
