Abstract
PURPOSE:To make it possible to allow an alternating current signal to pass through with no momentary break, by obtaining desired low-loss characteristics by increasing dv/dt dielectric strength without increasing the inflow of a gate current into a signal line. CONSTITUTION:Base terminals (anode gate) of equivalent transistors of the 1st conduction type of four-terminal thyristors 41 and 43 connected in reverse parallel are connected in common, and To base-emitter junctions of equivalent transistors of the 2nd conduction type, resistances 42 and 44 are connected in parallel which have resistance values meeting the requirement of desired dv/dt dielectric strength. In addition, diodes 45 and 46 for the prevention of a reverse current to the driving method are connected between cathodes and gates of thyristors 41 and 43. Between the common-connected anode gates and the connection point of diodes 45 and 46, a couple of amplifying methodes 47 and 48 are connected which amplify currents from driver circuits 49 and 50, have complementary input characteristics and are tolerant of an applied transient voltage.
