Wireless power receiving device and wireless power transmission device

摘要

A wireless power receiving device includes a voltage detection unit that detects an output voltage value of a rectifying unit, a power reduction unit that includes a switching element connected to a charging unit in parallel, and a control unit that controls operations of the switching element. In a case where the output voltage value detected by the voltage detection unit exceeds a first reference voltage value set in advance, the control unit controls and turns the switching element on by applying a voltage to the switching element, and controls the value of the voltage to be applied to the switching element so that the difference between the voltage value calculated on the basis of a current flowing in the switching element and a second reference voltage value set in advance decreases.
