A single-phase full controlled converted with RLE load will act like a line-commutated inverter when the firing angle α

A single-phase full controlled converted with RLE load will act like a line-commutated inverter when the firing angle α Correct Answer α > 90°

It will act like a inverter i.e. most of the current would flow from the battery or back emf E to the source. For α=90° it will not act like a converter nor an inverter.
