摘要：
According to one embodiment, in a power supply device, a power conversion circuit which outputs a power supply voltage to a load by converting the power supply voltage into a predetermined output voltage, and control circuit which has a ground potential which is different from that of the power conversion circuit, and controls the power conversion circuit are provided. In addition, a power supply circuit which supplies the power supply voltage to the control circuit by converting the power supply voltage into a control power supply which is insulated with respect to the ground voltage of the power conversion circuit.
