ABSTRACT:
An individual commutation for use with an inverter includes two resonant loops one of which is connected to the main current path adjacent each of the main thyristors. Each resonant loop includes a series coupled commutation capacitor and inductor together with commutation thyristor which is enabled to provide a commutation pulse to extinguish the load current through conducting main thyristor for a sufficient period to allow transition to the nonconducting state.
