Abstract

A control apparatus is provided which controls a power converter including a first circuit including first-side switching elements, and a second circuit including second-side switching elements and a choke coil. The control apparatus includes a current obtainment unit which obtains a value of current flowing through the choke coil, and a control unit which, when power is supplied from the second circuit to the first circuit, keeps a first-side switching element ON during a predetermined time period, before turning off at least one second-side switching element in an on state, the first-side switching element generating a reverse current in the second-side switching element to be turned off. The control unit performs control of keeping the first-side switching element ON during the predetermined time period and control of turning off the second-side switching element, on condition that the obtained value of the current is more than a predetermined command value.
