Question

For a full wave bridge inverter, the output voltage (Vo)

(a) Vo =  Vs/2    for 0 < t < T/2

(b) Vo =  Vs      for 0 < t <T/2

(c) Vo =  Vs      for T/2< t < T

(d) Vo = -Vs      for T/2< t < 3T/2

I have been asked this question during an interview.

The above asked question is from Single Phase VSI-3 in section Inverters of Power Electronics

Answer 1

Correct answer is (b) Vo =  Vs      for 0 < t <T/2

The explanation: For the first half cycle, Vo = Vs and for the second half cycle Vo = -Vs.
