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.

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, and
- wherein 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.
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 configured to receive the power from the resonance coil;
- a capacitor connected in parallel between the resonance coil and the load;
- a first switch configured to connect the resonance coil and the capacitor to each other;
- and
- a second switch configured to connect the capacitor and the load to each other,
- wherein the resonance coil is connected to the capacitor and the capacitor and the load are not connected to each other during a first interval, and
- wherein the resonance coil is not connected to the capacitor and the capacitor and the load are connected to each other during a second interval that is different from the first interval,
- wherein the first and second switches operate in opposite states during the first and second intervals.
