Abstract
A power conversion apparatus includes a switching circuit including multiple switching elements, and a control unit configured to control and switch the multiple switching elements included in the switching circuit at a predetermined switching frequency with a direct current voltage applied to an input terminal of the switching circuit. The switching circuit is configured to convert the direct current voltage applied to the input terminal and to output a converted electric current. The switching frequency is set such that the switching frequency and a main frequency component of a ripple occurring in the electric current are out of a frequency range used for communication with a vehicle-mounted receiver.
