<P>PROBLEM TO BE SOLVED: To assure use of an electric product that accompanies phase control and to avoid a switching loss from becoming excessive, related to an AC power supply. <P>SOLUTION: An inverter 16 converts a DC voltage of DC 216V outputted from a high voltage battery 12 into an AC voltage of AC 100V. The AC power outputted from the inverter 16 is supplied to an accessory power outlet 20 provided in a cabin. An inverter output switch 50 for a car driver to manually operate is connected to a control part 26 of the inverter 16. According to the on/off state of the inverter output switch 50, the voltage waveform of an AC power supply supplied to the accessory power outlet 20 which is outputted from the inverter 16 is selectively switched over between a sine wave AC and pseudo sine wave AC composed of rectangular waves. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
