<P>PROBLEM TO BE SOLVED: To provide a system linkage inverter device for a solar battery and a fuel battery that is reduced in cost and prevented in the deterioration of the fuel battery. <P>SOLUTION: The system linkage inverter device 3 is constituted such that: the maximum link voltage VAmax of a voltage adjusting means 11 is set lower than the maximum link voltage VBmax of a voltage adjusting means 12; when the output power of an inverter means 13 is restricted, first, an output voltage control circuit 25 controls a link voltage VAout not to exceed the maximum link voltage VAmax when both the link voltages VAout, VBout(=VCin) rise; and when the voltages still continue to rise, an output voltage control circuit 45 controls the link voltage VBout no to exceed the maximum link voltage VBmax(>VAmax). By this, the deterioration of the fuel battery 2 is prevented and cost reduction is achieved by making the solar battery 1 and the fuel battery 2 commonly use the inverter means 13. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
