Abstract
A power receiver which wirelessly receives power from at least one power source using one of magnetic field resonance and electric field resonance, including a power receiver coil, an internal circuit, a power detection resistor, a switch, a power reception control unit, and a communication circuit unit. The power receiver coil wirelessly receives the power from the power source, and the internal circuit uses the power obtained by the power receiver coil. The power detection resistor detects the power obtained by the power receiver coil, and the switch applies a received power voltage obtained by the power receiver coil by switching to the power detection resistor. The power reception control unit controls the power detection resistor and the switch, and the communication circuit unit performs communication with the power source, comprising detection information of a received power and power supply timing information.
