WIRELESS POWER RECEPTION DEVICES
First Claim
1. A wireless power reception device, comprising:
- a resonance coil configured to receive power from outside of the wireless power reception device in a magnetic resonance type;
a load coil inductively coupled to the resonance coil to receive the power from the resonance coil in an electromagnetic induction type; and
a load configured to receive the power from the load coil;
wherein the load coil is short-circuited and the load coil and the load are not connected to each other during a first interval, andwherein the load coil is not short-circuited and the load coil and the load are connected to each other during a second interval that is different from the first interval.

Abstract
A wireless power reception device may comprise a resonance coil configured to receive power from outside of the wireless power reception device in a magnetic resonance type; a load coil inductively coupled to the resonance coil to receive the power from the resonance coil in an electromagnetic induction type; and/or a load configured to receive the power from the load coil. The load coil may be short-circuited and/or the load coil and the load may not be connected to each other during a first interval. The load coil may not be short-circuited and/or the load coil and the load may be connected to each other during a second interval that is different from the first interval.
