Choose the correct statement.

(a) Circulating current type is faster in operation

(b) Non-circulating current type is faster in operation

(c) Both the types have the same speed of operation

(d) Circulating current improves power factor

The question was posed to me in quiz.

My doubt stems from Dual  Converters-2 topic in chapter Converters of Power Electronics

The correct choice is (a) Circulating current type is faster in operation

The best I can explain: In case of non-circulating type, to shift the operation from one mode to another mode a delay of 10 to 20msec is required to let the current decay to zero value and let the outgoing SCRs safely turn off. This delay is not required in case of circulating current mode.
