Title:
VOLTAGE REGULATOR
Document Type and Number:
Japanese Patent JP2018057135
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that it is difficult to promptly switch a tap to an optimal tap since there is a case that the tap is different from an assumed voltage regulated value when the tap is actually switched in a conventional voltage regulator.SOLUTION: A tap can be promptly switched to an optimal tap by a voltage regulator provided with: a discrimination part 151 which discriminates whether or not detection voltage detected by a voltage detection part deviates from a target voltage range; a voltage after assumption switching calculation part 152 which calculates voltage after assumption switching to be assumed after tap switching by using the detection voltage and voltage variation from the detection voltage when the tap is actually switched to the respective taps for one or two or more taps except a present tap when the detection voltage deviates from the voltage range; and a tap switching control part 154 which determines a switching destination tap by using the voltage after assumption switching of the respective taps calculated by the voltage after assumption switching to switch the tap set at present of a tap switching part to the switching destination tap.SELECTED DRAWING: Figure 4
