ユレータの起動回路。 The switching power supply is started by directing a portion of the input power to the drive power of the main switch, and after startup, the main switch is continuously driven by power via the auxiliary winding attached to the main transformer. In the separately-excited switching regulator, a diode is connected in series between the input voltage and the rectifying and smoothing part of the auxiliary winding, a voltage stabilizing circuit, and the output. The rectified and smoothed voltage value of the main transformer auxiliary winding is set higher than the set voltage value of the above-mentioned stabilizing circuit, and the rectified and smoothed voltage of the output of the main transformer auxiliary winding is applied to the input power supply by the diode that goes into the output of the voltage stabilizing circuit. A starting circuit for a separately excited switching regulator, characterized by a circuit configuration that prevents it from returning.
