WIRELESS POWER RECEIVER FOR INCREASED CHARGING EFFICIENCY
First Claim
1. A wireless power receiver configured to receive charging power from a wireless power transmitter, the wireless power receiver comprising:
- a power reception unit configured to receive the charging power from the wireless power transmitter;
a rectification unit configured to rectify charging power provided by the power reception unit, and output charging power in a form of Direct Current (DC);
a charging unit configured to store charging power; and
a power processing Integrated Chip (IC) that is connected to both the rectification unit and the charging unit, and is configured to convert a voltage of the rectified charging power, that the rectification unit has output, into at least one voltage, that an operation of the wireless power receiver requires, and output power having the at least one voltage.
