The main switching element switches the direct current to a high frequency and inputs it to a high frequency transformer.The outputs of the plurality of secondary windings of this transformer are rectified and smoothed by a rectifier circuit respectively to obtain a plurality of DC power supplies. In a multi-switching power supply in which the on/off ratio of the main switching element is controlled by voltage detection of one main DC power supply, and the other secondary DC power supplies are stabilized by respective regulators, the secondary DC power supplies are connected to the high frequency transformer. A switching element is provided in series between the secondary winding of the rectifying circuit and the rectifying circuit, and the on/off ratio of the switching element is controlled according to the output voltage of the rectifying circuit or the on/off ratio of the main switching element. A multi-switching power supply featuring a circuit.
