<P>PROBLEM TO BE SOLVED: To provide a system interconnection inverter device that can perfectly prevent the generation of a reverse power flow that effective power flows out to a system power side, with a simple equipment constitution without the necessity for preparing a pseudo load. <P>SOLUTION: The system interconnection inverter device that feeds AC power to a load connected to a system power supply 20 by inverting DC power to the AC power is provided with a control means 15 that controls an inverter 13 so that an effective current component of a current that flows out to the system power supply 20 becomes zero or minus with respect to a system power supply voltage. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
