<P>PROBLEM TO BE SOLVED: To charge a battery, such as a vehicular battery, without an exclusive battery charger. <P>SOLUTION: A power control apparatus has a vehicular battery 10, an inverter 14 and a motor 16. The positive electrode of the vehicular battery 10 is connected to a neutral point of a stator winding of the motor 16, and a negative electrode thereof is connected to a negative electrode of the inverter 14 on the DC side. A charge addition circuit 18 is provided that contains a diode rectifier connected between the positive electrode of the inverter 14 on the DC side and the positive electrode of the vehicular battery 10, and an external AC power supply 22 is connected to the inverter 14 through the charge addition circuit 18. By performing on-off control on a switching element on the positive electrode side of the inverter 14, the vehicular battery 10 is charged. <P>COPYRIGHT: (C)2010,JPO&INPIT |
