BOOST CONVERTER CONTROL APPARATUS

摘要

The present invention prevent a shortage of the output when an intermittent boost is executed. A control apparatus for controlling a boost converter that can boost power supply voltage by boost control has: an intermittent controlling device for executing the intermittent boosting in such a manner that output voltage is maintained in a voltage variation allowable range including a target value on the basis of the detected output voltage of the boost converter; an average value calculating device for calculating an average value of the output voltage in an execution period of the intermittent boosting; and a target value correcting device for correcting the set target value to increase it when the calculated average value is less than the target value and is less than a required voltage value of a loading apparatus.
