High voltage inverter commutation
Commutation failure is the most common disturbance in thyristor converters during inverter operation which can be triggered by different kinds of faults either the external faults (symmetrical or asymmetrical faults in the AC side, or the DC link to ground fault at the DC link side) [4] or by the internal faults such misfiring control or fault at the valves [5], the AC fault at sending end of the inverter can also leads to commutation failures.
