Consider the single-phase voltage source inverter circuit feeding an inductive load (L). Assume that the power MOSFET switches are ideal. S1 and S2 are switched on during the first 10 µs, and S3 and S4 are switched on during the next 10 µs in a switching cycle. The switches in the same leg are thus switched in a complementary fashion. Neglect the dead time. The waveform of the inductor current (iL) in the steady state is triangular with a peak value of 5 A as shown.
The rms value of the current through the switch S1 is:
The rms value of the current through the switch S1 is:
Correct : b
