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,
By rectifying and smoothing this voltage, it is isolated from the primary side of the converter transformer, and a stable secondary
A switching regulator for obtaining a DC power source, characterized in that a bidirectional constant voltage element is connected between the first DC power terminals. (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, a voltage is induced in 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
1. A switching regulator for obtaining a DC power supply, characterized in that a diode is connected between the first DC power supply terminals.
