ング電源。 A DC input power source, a first transformer, a second transformer, and a switch element are connected in series, and the first transformer stores magnetic energy during the ON period of the switch element, and stores that energy during the OFF period. In a switching power supply that supplies power to the load during the ON period of the switch element, the second transformer is connected to the first transformer in order to suppress the spike voltage that occurs when the switch element is turned off. A switching power supply characterized by having an auxiliary winding in the device.
