接続したことを特徴とするスイツチング電源。 DC input applied through a transformer is turned on and off by a switching element, the energy accumulated in the transformer during the on period of the switching element is rectified by a diode during the off period, and the rectified output is smoothed by a capacitor. In a switching power supply that obtains a DC output, an inductance element is inserted and connected to include the diode in series at a position before the capacitor, and the inductance element is connected in parallel with the inductance element and has a polarity opposite to that of the diode. A switching power supply characterized by having another diode connected in the relationship.
