源装置。A switching transistor converts the DC voltage on the input side into AC through a switching operation, a transformer transmits the AC voltage generated on the input side to the output side, and a transformer with a frequency corresponding to the magnitude of the DC output voltage obtained on the output side. It is equipped with a photocoupler to which a pulse signal is supplied, and a discharge circuit that detects the voltage on the light receiving side of the photocoupler and lowers the impedance between the base of the switching transistor and the ground (or power supply) only during the OFF period of the switching transistor. A switching power supply device characterized by:
