Abstract
A power conversion device includes switching elements, a reactor, and capacitors in each of which plural capacitor elements are connected in parallel to each other. Then, a carrier frequency used for controlling switching of the switching elements is set so that it is less than series resonance frequencies of all of the capacitor elements in the capacitors, and integer multiples of that frequency are each not equal to a parallel resonance frequency.
