タ。The voltage applied to the primary winding of the transformer is controlled intermittently by the switching operation of the switching means, and the voltage generated in the secondary winding of the transformer is output, and this voltage is compared with a reference voltage. In a DC-DC converter that controls the opening/closing operation of the switching means according to the comparison result to obtain a stable output, excitation voltage detection detects a part of the voltage that is intermittently applied to the primary winding of the transformer. and a smoothing means for applying the voltage detected by the excitation voltage detection means to one end and smoothing the voltage generated in the secondary winding of the transformer after rectifying it. converter.
