CONTROL APPARATUS FOR VOLTAGE CONVERSION APPARATUS

A control apparatus (30) for a voltage converting apparatus controls a voltage converting apparatus (12) configured to realize one-arm drive by alternatively switching on first and second switching elements (Q1, Q2). The control apparatus for the voltage converting apparatus is provided with: a switching control signal generating device configured to generate switching control signals (PWI1, PWI2) for changing on and off the respective first and second switching elements; a current detecting device configured to detect a current value (IL) of a drive current flowing through the first or second switching element, at rise timing of the switching control signal, when the one-arm drive is changed between one-arm drive using the first arm and one-arm driving using the second arm; a current estimating device configured to estimate an average value of the drive current by using the detected current value; and a current controlling device configured to control the drive current on the basis of the estimated average value.
