Question

The McMurray-Bedford half-bridge inverter requires

(a) 4 SCRs, 2 diodes, 2 capacitors and 2 inductors

(b) 4 SCRs, 4 diodes, 2 capacitors and 2 inductors

(c) 2 SCRs, 4 diodes, 2 capacitors and 1 inductor

(d) 2 SCRs, 2 diodes, 2 capacitors and 2 inductors

The question was asked in an interview for job.

This is a very interesting question from Force-Commutated Inverters in portion Inverters of Power Electronics

Answer 1

Right answer is (d) 2 SCRs, 2 diodes, 2 capacitors and 2 inductors

Easiest explanation: McMurray-Bedford type requires less number of SCRs and diodes as compared to the McMurray type, however the number of capacitors and inductors required is the same.
