For the circuit shown below to act as a line commutated inverter

(a) 180°>α>90° & E is removed

(b) 180°>α>90° & E is reversed

(c) 180°>α<90° & E is removed

(d) 180°>α<90° & E is reversed

This question was posed to me by my school principal while I was bunking the class.

Origin of the question is Single Phase FW AC-DC-5 in division Converters of Power Electronics

Correct option is (b) 180°>α>90° & E is reversed

Best explanation: For inverter operation the firing angle should be above 180 and E should be reversed.
