13 Claims

1. A power conversion apparatus comprising: a converter configured to convert AC power that is input from an AC power supply via a first conductive line pair, into DC power; an inverter configured to convert the DC power that is output from the converter to a second conductive line pair, into the AC power; and a capacitor connected between conductive lines of the first conductive line pair or between conductive lines of the second conductive line pair, wherein, letting an inductance of an inductance component from a point where the power conversion apparatus is connected to the AC power supply, to the capacitor, be L a maximum value of output frequency of the inverter be MAX(fo), −C, which is a capacitance of the capacitor (C), satisfies
