<P>PROBLEM TO BE SOLVED: To improve power factor to a system seen from a generator in a system interconnecting generator. <P>SOLUTION: In the system interconnecting generator which is connected to a commercial power system, an AC switch 17 is provided with a pair of AC terminals (T<SB>A3</SB>, T<SB>A4</SB>) to be connected to the commercial power system 16 and a pair of DC terminals (T<SB>D3</SB>, T<SB>D4</SB>) into which specified DC output flows, a choke coil 12 is inserted between the DC output terminal T<SB>D1</SB>and the pair of DC terminals T<SB>D3</SB>, and a control circuit 15 controls the switching of the polarity of the AC switch 17 equipped with switches 14a, 14b, 14c, 14d based on the waveform information of the commercial power system 16. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
