Abstract:
PROBLEM TO BE SOLVED: To provide a power converter capable of ensuring safety easily, when switching the AC powers for system interconnection and system independence of output voltages different from each other.SOLUTION: A power converter includes a system interconnection relay 5 outputting an AC power for system interconnection of an inverter circuit 2 by relay on during system interconnection mode, and an independence relay 7 connected in parallel with the system interconnection relay 5, and outputting an AC power for independence of an output voltage different from the system interconnection of the inverter circuit 2 by relay on during independent mode. A protection switch circuit 8 operates to interrupt connection of the system interconnection relay 5 and the independence relay 7, even if the independence relay 7 is operated erroneously relay on, when the system interconnection relay 5 is relay on and the independence relay 7 is relay off.
