Abstract
A power conversion apparatus comprising a switching power module (,) for conducting power conversion in a switching manner, a plurality of smoothing capacitors (,A) for smoothing a direct-current power supply output to be applied to the switching power module (,), and a switching power module connecting wiring board (,) for establishing connection of the smoothing capacitor (,A) to the switching power module (,). A ceramic capacitor is used as the smoothing capacitors (,A). The smoothing capacitors (,A), a smoothing capacitor case (,) accommodating the ceramic capacitors and the switching power module connection wiring board (,) are integrated structurally with each other to construct a smoothing capacitor assembly (,). This smoothing capacitor assembly (,) is connected to the switching power module (,).
