WIRELESS POWER RECEPTION DEVICES

摘要

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.
