<P>PROBLEM TO BE SOLVED: To achieve high-precision voltage compensation while inexpensively miniaturizing a voltage variation compensation device in the voltage variation compensation device for suppressing voltage variations supplied to a load. <P>SOLUTION: The voltage variation compensation device compensates the voltage variations of a power line to be connected. The device includes a plurality of voltage compensation circuits, which output stored power while being connected with a plurality of power accumulation means for accumulating power of a prescribed value, and a control circuit for controlling a plurality of the voltage compensation circuits so as to allow them to output first polarity power of a prescribed value and second polarity power of a prescribed value, which has a polarity opposite to a first polarity, to the load. A plurality of the voltage compensation circuits are connected in series. The control circuit accumulates power output from one voltage compensation circuit into the power accumulation means connected to the other voltage compensation circuits and controls the power so as to become the first polarity power of a prescribed value or the second polarity power of a prescribed value. <P>COPYRIGHT: (C)2007,JPO&INPIT |
