Abstract
Provided is a power conversion unit, in which a power smoothing capacitor is configured such that a plurality of unit capacitors as conductive polymer hybrid aluminum electrolytic capacitors are arrayed in a grid pattern and connected in parallel on a circuit board, and also connected to a plurality of unit modules of different phases via positive and negative bus bars arranged on both sides of the circuit board so that each group of several unit capacitors and each unit module are arranged close to each other, to thereby reduce wiring impedance of a power supply circuit and suppress noise generation.
