ングレギユレータ。 One terminal of a rectifier diode is connected to one end of the secondary winding of the transformer, one terminal of a flywheel diode is connected to the other end, and a series circuit of a reactor and a smoothing capacitor is connected in parallel with the flywheel diode. A load is connected between the terminals of the smoothing capacitor, and DC power is supplied to the load via the rectifier diode when at least one switching element connected in series to the primary winding of the transformer is turned on. In a switching regulator that stores energy in a reactor and releases the energy stored in the reactor to a load via the flywheel diode when turned off, a diode in a direction opposite to the flywheel diode is connected in parallel with the flywheel diode. and a capacitor are connected in series, and a resistor is connected between this series connection point and one terminal of the smoothing capacitor.
