POWER RECEPTION APPARATUS, POWER RECEPTION METHOD, AND WIRELESS POWER FEED SYSTEM

Abstract

A power reception apparatus includes: a power receiver to receive wireless power; a switching rectifier circuit including rectifiers with different power conversion characteristics and configured to rectify received power using a target rectifier selected from among them; a detector configured to detect output voltage or output power of the target rectifier; a power converter configured to control the output voltage of the target rectifier; a storage battery configured to be charged with or discharge output power of the power converter; and a controller configured to estimate the received power based on (i) the output voltage and information indicating a relationship between input power and output voltage of the target rectifier, or (ii) the output power and information indicating a relationship between input power and output power of the target rectifier. The controller further controls operations of the switching rectifier circuit and the power converter based on the estimated received power.
