Title:
DRIVING DEVICE FOR THREE-TERMINAL THYRISTOR
Document Type and Number:
Japanese Patent JPS5886867
Kind Code:
A
Abstract:
PURPOSE:To give safety while miniaturizing the device by completely isolating a switch for remote control from an AC power supply by a pulse transformer and a gate control signal transmission means. CONSTITUTION:A trigger pulse signal generator is formed by a resistor 10, a capacitor 11, a trigger element 12 and the primary winding of the first pulse transformer 13. When closing the switch 14, trigger pulse signals control the gate of a bidirectional three-terminal thyristor 9 through the gate control signal transmission means 15. The gate control signal transmission means 15 outputs signals controlling the gate from the output side by signals transmitted to the input side under a state that the switch 14 is isolated from the AC power supply 7, and the primary side and the secondary side are isolated.
