A power conversion apparatus includes a pair of switching elements that are connected in series between a higher potential side terminal and a lower potential side terminal to form upper and lower arms; a coil whose end is connected between the pair of switching elements; and a controller that calculates, based on a voltage between the higher potential side terminal and the lower potential side terminal and an inductance of the coil, a time rate of change of a current value of a current flowing through the coil, and switches, based on the calculated time rate of change of the current value, between a single arm drive mode in which only one of the pair of switching elements is driven to be turned on/off and a double arm drive mode in which the pair of switching elements are driven to be turned on/off in opposite phase.
