ABSTRACT:
A method for triggering a high voltage solid state switch comprised of a set of thyristors connected in series. Initiating switch turn-on requires command triggering of only the lowest voltage thyristor, thereby eliminating the need for expensive high voltage pulse transformers or optically isolated triggers. Triggering of one thyristor causes a redistribution of voltage across the switch, generating a current flowing through the snubber circuit across each untriggered thyristor. This current is coupled to the gate of each thyristor causing all of them to turn on simultaneously. This results in an inexpensive method for triggering a high voltage solid state switch.
