Question

A single phase full bridge inverter using transistors and diodes is feeding a R load of 3 Ω with the dc input voltage of 60 V. Find the rms output voltage and the peak reverse blocking voltage of each transistor.

(a) 30 V, 60 V

(b) 30 V, 30 V

(c) 60 V, 60 V

(d) 60 V, 30 V

The question was posed to me in a dream while sleeping

My question is based upon Quality of Inverters in section Inverters of Power Electronics

Answer 1

Right choice is (c) 60 V, 60 V

Easy explanation: Rms output voltage = PIV of each transistor = Vs. Vs = 60 V.
