Abstract

PURPOSE: To avoid the application of a high voltage to an optical auxiliary thyristor, by connecting in pararel a series connection set of thyristors of the same polarity in a reversed polarity and connecting one end of an optical auxiliary thyristor another end of which is connected to the interconnection point of the thyristor sets to pulse transformers for thyristor triggering via diodes.
CONSTITUTION: When an optical auxiliary thyristor PTH1 is triggered with a forward voltage given to main thyristors TH1 and TH3, a trigger pulse is applied to a pulse transformer PT1 only and the main thyristors TH1 and TH3 are triggered. In this case, a diode D2 is reversingly biased and the voltage of the main thyristor TH3 or TH4 only is applied to the thyristor PTH1. When the nain thyristors TH2 and TH4 are at forward voltage, the diode D2 is conductive and the main thyristors TH2 and TH4 are triggered.
