An equivalent circuit of a converter () is represented by a series connection between an equivalent capacitor () and an equivalent resistor (), and the converter () includes a controller that adjusts a power factor of the input power by controlling a capacitive reactance (Xc) of the equivalent capacitor ().

Converter and power receiving apparatus

An electric power receiving device in one aspect of embodiments of the present disclosure comprises an electric power receiving section and a converting section. The converting section comprises a compensation voltage generating section. The compensation voltage generating section generates a compensation voltage capable of canceling out a reactance component in the electric power receiving section, and applies the compensation voltage to the electric power receiving section. The compensation voltage generating section comprises a phase changing section, a physical quantity detecting section, and a searching section. The searching section searches a target phase of the compensation voltage that brings the electric power receiving device into a substantially resonant state, based on a physical quantity detected by the physical quantity detecting section. The compensation voltage generating section determines the compensation voltage having the target phase as the compensation voltage to be applied to the electric power receiving section.
