Abstract

PURPOSE:To operate the thyristor stably and efficiently with respect to all the available frequencies by spacing a gate source and the gate cathode terminal of a gate turn-off thyristor GTO by a switching element. CONSTITUTION:When a transistor Tr3 is turned on, a current flows from a power source 2 through an emitter base of a transistor Tr5, a resistor 4 and a transistor Tr3 to turn on the transistor 5. An on-gate current flows through a resistor 6 to the gate turn-off thyristor GTO1. Then, when the Tr3 is turned off and the transistor Tr7 is turned on, a power source 2, Tr7, resistor 8, and transistor 9 are turned off, and hence a current flows through the buses of the transistor 7, diode 10 and transistor 9, GTO1 is turned off. Accordingly, a gate current stable regardless of the operating frequency of the GTO is caused to flow through GTO, whereby the thyristor can be efficiently operated.
