<P>PROBLEM TO BE SOLVED: To provide a separate power supply system which enables both of AC electric load and DC electric load to be used, and can prevent the damage of a power converter in case that a current over the range of specification flows or in case that input voltage is over the range of specification by an error in connection of a storage battery. <P>SOLUTION: A control circuit 15 supplies AC power by driving a boosting circuit 10 and an inverter bridge 11, and supplies DC by turning on a switch 13. In case that the current over the range of specification flows, or in case that the input voltage is over the range of specification, the control circuit 15 stops the boosting circuit 10 and the inverter bridge 11, and also stops the power supply by turning off the switch 13. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
