WIRELESS POWER RECEIVING APPARATUS
First Claim
1. A wireless power receiving apparatus configured to receive an electric power signal including any one of an electric field, magnetic field, or electromagnetic field, transmitted from a wireless power supply apparatus, the wireless power receiving apparatus comprising:
- a reception coil configured to receive the electric power signal;
a resonance capacitor arranged together with the reception coil to form a resonance circuit;
a load circuit;
a switch configured to switch the state between a first state in which the load circuit is connected in series with the resonance circuit comprising the reception coil and the resonance capacitor and a second state in which the load circuit is disconnected from the resonance circuit; and
a control unit configured to control the switch so as to alternately switch the state between the first state and the second state in a time sharing manner.

Abstract
A wireless power receiving apparatus receives an electric power signal including any one of an electric field, magnetic field, or electromagnetic field, transmitted from a wireless power supply apparatus. A resonance capacitor is arranged together with a reception coil to form a resonance circuit. A switch is provided in order to switch the state between a first state in which the load circuit is connected in series with the resonance circuit including the reception coil and the resonance capacitor and a second state in which the load circuit is disconnected from the resonance circuit. A control unit controls the switch so as to alternately switch the state between the first state and the second state in a time sharing manner.
