<P>PROBLEM TO BE SOLVED: To provide a power supply device that can simultaneously perform charging of a first battery and power supply to a second battery side lower in voltage than the first battery from an AC power source. <P>SOLUTION: A control circuit 66, while feeding back the output to a high-voltage battery B1, performs control of a first H-bridge circuit 54 and a second H-bridge circuit 56 on a primary winding 57a side, and in addition, performs control of a third H-bridge circuit 58 on a first secondary winding 57b side of a transformer 57 to charge the high-voltage battery B1 from a commercial power source 67. At the same time, the control circuit 66, while adjusting the output voltage to an accessory battery B2 by a voltage adjustment circuit 63 on a second secondary winding 57c side, supplies power to the accessory battery B2 side from the commercial power source 67. <P>COPYRIGHT: (C)2012,JPO&INPIT |
