チング回路。[Claims for Utility Model Registration] A switching device comprising a bias circuit that applies a bias to an output transistor that drives an output transformer, a reverse bias circuit that applies a reverse bias to the transistor, and an oscillation circuit that controls the operation of the reverse bias circuit. In the circuit, the bias circuit and the oscillation circuit are driven so that their operations are synchronized, and there is a connection between the reverse bias circuit and the oscillation circuit so that the operation of the reverse bias circuit and the operation of the oscillation circuit are reversed. A switching circuit characterized in that a constant voltage diode is connected.
