Title: Semiconductor for controlling dc power supply
Inventor: YABUKI MANABU
IPC: H02M3/155
Filed: 1979-01-13
Abstract: PURPOSE:To perform switching control of a connected thyristor independently by using a junction capacity of a transistor. CONSTITUTION:Positive-output voltage and current are supplied to a collector C, negative-output voltage and current are supplied to a cathode K, and a specified amount of base voltage and current are applied to a base B and also to a gate G via a gate circuit 9. The gate circuit 9 receives the voltage and current from the base B, transforms the gate driving power to the magnitude of the controlled gate- driving voltage, and supplies it to the gate terminal G. The DC component of the positive and negative output voltage are cut out because a transistor 1 having a gain of hFE accompanied by storage capacity C1 is used. The base voltage and current and the collector current having a gain of hFE of the transistor 1 a companied by the base-leak current are applied to the anode of a thyristor 2 as an emitter current.
