Abstract

See full text

A power conversion system in which a converter and an inverter are coupled to each other via a DC coupling unit that has an inductance component is provided. A switching frequency of each of the converter and the inverter is set to be the same and the switching frequency is set to be higher than a resonance frequency of a resonance circuit that includes a first capacitor, a second capacitor, and the DC coupling unit such as a cable. A switching operation of at least one of the converter or the inverter is controlled such that phases of predetermined components of voltage ripples, at the first capacitor and the second capacitor, that are respectively generated by switching operations of the converter and the inverter are substantially matched.
