る電源装置。[Claims for Utility Model Registration] A smoothing capacitor connected to the output side of the rectifying element, and a first smoothing capacitor connected in parallel with the smoothing capacitor.
a series circuit of a switching element and a supplementary capacitor, a second switching element connected in parallel with the first switching element, and a comparison circuit for comparing the output voltage of the smoothing capacitor with a reference voltage. When the output voltage of the smoothing capacitor is higher than the reference voltage, the first switching element is turned on by the output of the comparison circuit, and the supplementary capacitor is charged by the smoothing capacitor. When the output voltage of the replenishing capacitor becomes lower than the output voltage of the replenishing capacitor, the second switching element is turned on, and power is supplied to the load from the replenishing capacitor in addition to the smoothing capacitor. Features a power supply device.
