Title:
Electricity-receiving device
Document Type and Number:
Japanese Patent JP6144955
Kind Code:
B2
Abstract:
Provided is a power reception device in which power consumption at the time of wireless power supply is reduced. A power reception device is provided with a power reception control device capable of temporarily stopping supply of power supply voltage to a communication control unit for controlling communication in a break period of communication intermittently performed between a power transmission device and a power reception device. In the structure, a clock signal is generated on the basis of a power receiving signal transmitted from the power transmission device, and a period of communication intermittently performed can be measured using the clock signal. Further, a structure may be employed in which supply of power supply voltage to the communication unit in the power reception control device can be stopped in the break period of the communication.
