MGVCL Exam Paper (30-07-2021 Shift 2)
A MOSFET rated for 15 A, carries a periodic current as shown in figure. The ON state resistance of the MOSFET is 0.15 Ω. The average ON state loss in the MOSFET is

33.8 W
3.8 W
15 W
7.5 W

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Ip = 10 A
Ton = π
T = 2π

Iavg = Ip*√(Ton/T)
Iavg = 10*√(1/2)
= 7.07 A
The average ON state loss in MOSFET, P = Iavg²*R
P = 7.07²*0.15
P = 7.5 W
