POWER RECEIVING DEVICE, POWER FEEDING DEVICE, AND ELECTRONIC APPARATUS
First Claim
1. A power receiving device comprising:
- a power generator including a power receiving element that receives a power signal supplied in a wireless manner from a power feeding device, the power generator generating direct current power on a basis of the power signal;
a detector including a detection element, the detector driving the detection element and detecting an alternating current signal generated in the detection element, during a power receiving period in which the power receiving element receives the power signal; and
a controller that controls the power feeding device on a basis of a detection result of the detector.

Abstract
A power receiving device of the disclosure includes a power generator, a detector, and a controller. The power generator includes a power receiving element that receives a power signal supplied in a wireless manner from a power feeding device, and generates direct current power on the basis of the power signal. The detector includes a detection element, and drives the detection element and detects an alternating current signal generated in the detection element, during a power receiving period in which the power receiving element receives the power signal. The controller controls the power feeding device on the basis of a detection result of the detector.
