<P>PROBLEM TO BE SOLVED: To continue the operation of a wind power generator without using a secondary battery even when a fault occurs in the secondary battery which can be connected directly to a DC between a rectifier and an inverter without supplying overcurrent. <P>SOLUTION: A wind power generator includes a rectifier 3 for rectifying an AC output of the wind power generator into a DC voltage, the inverter 5 for converting a wind power generator output converted into the DC voltage into an AC voltage, the DC having a smoothing capacitor 4 for connecting the rectifier 3 to the inverter 5, the secondary battery 9 having a switch 10 connected directly to the DC and a current limiting switch 8 connected to the DC via a current limiter circuit 7, and a switching controller 26 for comparing the secondary battery voltage with the smoothing capacitor voltage to close the switch 10 for connecting the secondary battery 9 directly to the DC when the secondary battery voltage substantially coincides with the smoothing capacitor voltage. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
