Abstract: A DC power supply apparatus includes a charging circuit, which charges a secondary battery of a vehicle from an AC power source device or a DC power source device. The charging circuit includes a non-insulating converter circuit and an insulating converter circuit. A breaker relay disconnects the AC power source device and the charging circuit in an initial charging period to supply a large charging current to the secondary battery by the non-insulating converter circuit. As a result, charging can be performed with high efficiency without the insulation transformer. The breaker relay connects the AC power source device and the charging circuit after the initial charging period. Only the insulating converter circuit supplies the charging current to the secondary battery. Thus, adverse effect of stray capacitance of a circuit of the vehicle can be eliminated.

Abstract: In a power supply apparatus, a power source generates electric power at a predetermined source voltage. The first converter circuit converts the source voltage into a first voltage or a second voltage. The secondary battery is charged with electric power at the first voltage when the first converter circuit outputs electric power at the first voltage. The second converter circuit converts the first voltage of the electric power outputted from the first converter circuit or the secondary battery into the second voltage. The electric load device is supplied with electric power at the second voltage outputted from the second converter circuit. The direct power supply circuit directly supplies electric power at the second voltage outputted from the first converter circuit to the electric load device without passing through the second converter circuit when the first converter circuit outputs the electric power at the second voltage.
