イツチング電源。 The main switching element switches the direct current to a high frequency and inputs it to a high frequency transformer.The outputs of the multiple secondary windings of this transformer are rectified and smoothed by a rectifier circuit to obtain multiple DC power supplies. In a multi-switching power supply in which the on/off ratio of the main switching element is controlled by detecting the voltage of one main DC power supply, and the other secondary DC power supplies are stabilized by respective regulators, the transformer is connected to the secondary winding. Among them, the winding for the secondary DC power supply is a winding with a tap, and a switching element is provided between each tap of this winding and the rectifier circuit, and the output voltage of the rectifier circuit or the on/off ratio of the main switching element is adjusted. 1. A multi-switching power supply, comprising: a control circuit that selectively turns on the switching element according to the switching element.
