タ。[Claims for Utility Model Registration] (1) An auxiliary rectifier circuit connected to an AC power source via a circuit breaker and a smoothing capacitor, and the switching element in the switching circuit is driven by the smoothing capacitor. In a switching regulator where control power is supplied to the circuit and the control circuit, a thyristor is connected to one terminal of the smoothing capacitor, and through this thyristor, control power is supplied at startup and the switching circuit is supplied with control power. The control power supply after startup is directly supplied from the auxiliary winding provided in the high frequency transformer in the thyristor via the rectification and smoothing circuit, and the control power supply voltage at startup is lower than the control power supply voltage after startup, and the gate of the thyristor is A switching regulator, characterized in that a series circuit of a constant voltage diode and a resistor is connected between the other terminal of the smoothing capacitor. (2) The switching regulator according to claim 1 of the utility model registration, which comprises a step-down transformer interposed between the circuit breaker and the auxiliary rectifier circuit.
