By switching the DC power supply with a switching element, an alternating current is passed through the primary coil of the transformer, and a DC output obtained by rectifying the AC output generated in the first secondary coil of the transformer is supplied to the first load. and a switching power supply that controls the switching element so that the DC output voltage always maintains a predetermined value, and supplies the AC output generated in the second secondary coil of the transformer to a second load. A switching device comprising: a first resistor connected in parallel to the primary winding; and a second resistor inserted between the primary winding and the switching element. power supply.
