特徴とする低リツプル電源装置。 A tap provided on the primary side of the main transformer, an oscillator that generates an output signal according to the secondary output voltage of the main transformer, and a control that selects the tap according to the secondary output voltage of the main transformer. It is characterized by comprising an up-down counter that emits a signal, and a forward converter that shifts the voltage phase on the primary side of the main transformer in accordance with the output signal of the oscillator and the control signal of the up-down counter. Low ripple power supply.
