スイツチングレギユレータ。[Claims for Utility Model Registration] 1. A rectifier and smoothing circuit 10 that accepts an AC power source;
A resistor R for inrush current limitation placed in this rectifying and smoothing circuit, and a thyristor T bypassing this resistor.
RC, and at least two for obtaining mutually independent DC outputs from the DC voltage obtained by the rectifying and smoothing circuit.
It has two systems of switching regulators 1 and 2, the trigger voltage of the thyristor is obtained from either one of the two switching regulators, and the switching system that supplies the trigger voltage to the thyristor When the switching regulator 1 of the system in question reduces its output or stops operating due to the overcurrent or overvoltage protection circuit P1 provided in the regulator 1, the switching regulator 2 of the other system also shuts down. A multi-output switching regulator configured to reduce output or stop operation. 2. A rectifying and smoothing circuit 10 that receives AC power;
A resistor R for inrush current limitation placed in this rectifying and smoothing circuit, and a thyristor T bypassing this resistor.
RC, and at least two systems of switching regulators 1 and 2 for obtaining mutually independent DC outputs from the DC voltage obtained by the rectifying and smoothing circuit, and the trigger voltage of the thyristor is set by two switching regulators. The switching regulator of the system is activated by the operation of the remote ON/OFF circuit provided in the switching regulator 1 of the system that supplies the trigger voltage to the thyristor. This multi-output switching regulator is configured so that when the regulator 1 stops operating, the switching regulator 2 of the other system also stops operating.
