ツチングレギユレータ。[Claims for Utility Model Registration] A switching circuit that intermittently converts an input voltage into an alternating current voltage; a filter that includes a choke coil and a first capacitor and smoothes the alternating current voltage into a direct current to obtain a first output voltage; , a switching regulator comprising a flywheel diode that discharges the electric charge accumulated in the choke coil when the switching circuit is turned on, when the switching circuit is turned off, the switching circuit comprising: a connection point between the switching circuit and the filter; and a reference potential. A series circuit consisting of a capacitor and a second diode is connected between the points and the cathode of the second diode is connected to the reference potential, and a cathode of a rectifying diode is connected to the anode of the second diode. A switching device characterized in that, by connecting a smoothing capacitor between the anode of the rectifying diode and a reference potential point, a second output voltage having a polarity opposite to the input voltage is obtained from the smoothing capacitor. Regulator.
