Q1:

McMurrary full bridge inverter uses

A auxiliary commutation

B complementary commutation

C natural commutation

D any of the above

ANS:A - auxiliary commutation

McMurray-Bedford half-bridge inverter. McMurray-Bedford inverter is a complementary impulse commutated inverter. This means that if two inductors are tightly coupled, tringgering of one thyristor turns-off another thyristor in the same arm. This circuit configuration uses less numbers of thyristors and capacitors are higher.
