スイツチングレギユレータ。[Claims for Utility Model Registration] (1) A first DC power source is obtained by rectifying and smoothing an AC input, and the primary winding of a converter transformer and a switching element are connected in series to both ends of this first DC power source. , a voltage is induced in the secondary winding of the converter transformer by turning on and off the switching element with an appropriate on/off ratio using a signal from the control section,
In a switching regulator that rectifies and smoothes this voltage, it is isolated from the primary side of the converter transformer and obtains a stable second DC power supply, in parallel with a smoothing capacitor that rectifies and smoothes the AC input. A switching regulator characterized by being equipped with a capacitor for absorbing abnormal voltage. (2) A first DC power source is obtained by rectifying and smoothing the AC input, and the primary winding of the converter transformer and a switching element are connected in series to both ends of this first DC power source, and switching is performed by a signal from the control unit. By switching the element on and off with an appropriate on/off ratio, voltage is applied to the secondary winding of the converter transformer,
By rectifying and smoothing this voltage, it is isolated from the primary side of the converter transformer, and a stable secondary
In a switching regulator that obtains a DC power supply, a polar smoothing capacitor for rectifying and smoothing the AC input is connected in parallel with a diode connected in series so that each polarity is opposite to that of the smoothing capacitor. A switching regulator characterized in that it is equipped with a capacitor for absorbing abnormal voltage consisting of a polar electrolytic capacitor.
