Abstract
A power conversion apparatus includes an input side terminal, an output side terminal and a switch unit, switching the switch unit between ON and OFF during a power transmission. The switch unit has characteristics that, in the case where a reverse current flows through the switch unit, the larger a gate voltage thereof in a negative side, the larger a conduction loss occurring when the reverse current flows. The power conversion apparatus is provided with a control unit that increases, when determined that the increase request for increasing the heating value is present, the gate voltage of the switch unit to the negative side when turned OFF compared to a case where no increase request for increasing the heating value is present, the reverse current flowing through the switch unit during the power transmission.
