Original Abstract Submitted
An isolated power supply device includes a plurality of transformers having input windings and cores. The input windings are connected to a DC power supply. Output sides of the transformers are connected to power feeding targets. At least two of the transformers have control windings. The isolated power supply device includes a control switch, control wirings, and a common wiring. First terminals of the control windings are connected to the ground. Second terminals of the control windings are connected to first terminals of the corresponding control wirings. Second terminals of the control wirings are connected to the common wiring. The isolated power supply device further includes a control unit that turns on and off the control switch based on a voltage value of the common wiring.
