Abstract
An object of the present invention is to provide a highly efficient power supply device. A power supply deviceaccording to the present invention includes a bidirectional DC-DC converterand an insulated DC-DC converter. The bidirectional DC-DC converterreceives a main batteryand outputs a direct-current link voltage Vlink. The insulated DC-DC converterreceives the link voltage Vlink and supplies power to a load. The link voltage Vlink, which is an output of the bidirectional DC-DC converter, changes according to the output voltage of the insulated DC-DC converter
