Title: Switching circuit
Inventor: YABUTA AKIRA
IPC: H03K17/73
Filed: 1986-10-15
Abstract: PURPOSE:To realize fast switching, by impressing a controlled voltage between the gate and the cathode of an electrostatic induction thyristor through a triggering MOS type FET, connecting a short-circuiting MOS type FET in parallel, and controlling both MOS type FETs based on a switching control signal. CONSTITUTION:The titled circuit is constituted of a trigger circuit A in which the controlled voltage is impressed between the gate and the cathode of the electrostatic induction thyristor Ts via the triggering MOS type FET Q17, and also, the short-circuiting MOS type FET Q18 is connected in parallel between the gate and the cathode of the electrostatic induction thyristor Ts, and which controls the ON and OFF of the electrostatic induction thyristor Ts by controlling both MOS type FETs based on the switching control signal Vs, and the circuit A is formed so as not to trigger the MOS type FETs Q17 and Q18 simultaneously. In such way, since the MOS type FETs Q17 and Q18 are prevented from being triggered simultaneously, it is possible to prevent damage due to excess current from being generated in the MOS type FETs Q17 and Q18.
