<P>PROBLEM TO BE SOLVED: To provide a battery charger which converts an AC power output from an external AC power supply to a DC power at a conversion circuit and can adjust an output voltage of the conversion circuit when the DC power is supplied to the battery. <P>SOLUTION: A charger 10 of a battery 12 includes a DC/DC converter 20 and an inverter 22. Further, the charger 10 of the battery 12 includes first wiring 44 for charge which can connect an AC power supply 14 between wiring 35 which is connected to the inverter 22 via a rotary electric machine 34 and wiring 43 which connects the DC/DC converter 20 to the inverter 22. Furthermore, the charger 10 of the battery 12 includes a control part 38 which converts an AC power of the inverter 22 to a DC power by controlling a switching element 30 provided in the inverter 22 and steps down a voltage value of the converted DC power to be equal to or less than an upper limit voltage value of the battery 12 by controlling the switching element 30 provided in the DC/DC converter 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
