VSIs using GTOs are turned off by

(a) load commutation

(b) line commutation

(c) applying a negative gate pulse

(d) removing the base signal

This question was posed to me in an interview.

This is a very interesting question from Single Phase VSI-1 in division Inverters of Power Electronics

The correct choice is (c) applying a negative gate pulse

To explain I would say: GTOs are gate turn off SCRs in which turn-off is achieved by applying a negative gate pulse.
