Beschreibung
Zusammenfassung:	A power supply device 1 according to the present invention includes a bidirectional DC-DC converter 3 and an insulated DC-DC converter 4. The bidirectional DC-DC converter 3 receives a main battery 5 and outputs a direct-current link voltage Vlink. The insulated DC-DC converter 4 receives the link voltage Vlink and supplies power to a load 7. The link voltage Vlink, which is an output of the bidirectional DC-DC converter 3, changes according to the output voltage of the insulated DC-DC converter 4.
