Abstract

A power conversion apparatus includes a power conversion circuit portion which includes a plurality of semiconductor switching elements, a control signal generation portion which generates a control signal for controlling opening and closing of each of the semiconductor switching elements, a plurality of driving portions which drive the semiconductor switching elements, and a first board on which the power conversion circuit portion and the plurality of driving portions are mounted. Each of the driving portions includes a power supply portion which converts AC power-supply power input from outside the first board into DC power-supply power, and a driving signal generation portion which generates a driving signal for driving the semiconductor switching elements from the DC power-supply power in accordance with the control signal.
