<P>PROBLEM TO BE SOLVED: To solve a problem wherein the operation efficiency of a fuel cell power generator is deteriorated sharply if a trouble occurs in a system power supply. <P>SOLUTION: This power conditioner device 15 comprises: an inverter 22 that is arranged between the fuel cell power generator 11 and the system power supply 12 to convert electric power generated by the fuel cell power generator into AC power; a systematically interconnecting switch 23 that connects or disconnects a main load 13 and the inverter; and a CPU 25 that is systematically connected to the system power supply to control the change-over of the switch so as to supply the output power of the inverter to the main load. The device also has an SSR circuit 24 that connects or disconnects a sub-load 14 and the inverter. When a trouble of the system power supply is detected through a system monitor 33 during the systematically interconnecting operation, the CPU connects the inverter and the sub-load, controls the change-over to the SSR circuit so as to supply all AC power converted by the inverter to the sub-load, and then controls the change-over of the systematically interconnecting switch so as to disconnect the main load from the inverter. <P>COPYRIGHT: (C)2007,JPO&INPIT |
