Abstract: A power supply unit accommodates a main DC/DC converter and an AC charger (a charging circuit, a sub-DC/DC converter) in a housing. The main DC/DC converter and the sub-DC/DC converter are arranged in the same tier of the housing. The charging circuit is arranged in a tier different from that of the main DC/DC converter and the sub-DC/DC converter. The main DC/DC converter and the sub-DC/DC converter arranged in the same tier of the housing are controlled to operate in a mutually exclusive manner.
