<P>PROBLEM TO BE SOLVED: To provide a voltage compensator for compensating a reduction in voltage supplied to a load from a power supply without losing power. <P>SOLUTION: The compensator is provided with a voltage detection means measuring voltage supplied from the power source to the load, a storage means storing prescribed voltage, a determination means determines whether voltage that the voltage detection means measures is lower than prescribed voltage stored in the storage means or not, a voltage applying means reducing voltage supplied to the load from the power supply by a difference with voltage obtained by measuring power voltage to be prescribed voltage, a first switch formed between the power supply and the load, a second switch disposed between the power supply and the voltage application means or between the load and the voltage application means and a switch control means turning off the first switch when measured voltage is determined to be lower than prescribed voltage and turning off the second switch and turning on the first switch when voltage measured by turning on the second switch is determined to be not less than prescribed voltage based on a result that the determination means determines. <P>COPYRIGHT: (C)2008,JPO&INPIT |
