Patent ID: 10897209

Abstract:
In the power supply device, the insulated transformer transforms the voltage of alternating-current power. The rectifying circuit rectifies the alternating-current power transformed by the transformer to direct-current power. The smoothing inductor smoothes the direct-current power rectified by the rectifying circuit. The first output terminal outputs the direct-current power smoothed by the smoothing inductor. The second output terminal is a terminal different from the first output terminal and outputs the direct-current power smoothed by the smoothing inductor. An FET is provided between the smoothing inductor and the first output terminal and adjusts a current output from the smoothing inductor to the first output terminal. An FET is provided between the smoothing inductor and the second output terminal and adjusts a current output from the smoothing inductor to the second output terminal. The controller controls the FET and the FET.
