POWER RECEIVER FOR WIRELESS CHARGING SYSTEM
First Claim
1. A power receiver for a wireless power transmission system, the power receiver comprising:
- input circuitry that converts power transmitted wirelessly from a power transmitter into an input signal; and
a regulator, connected to the input circuitry, that regulates the input signal to generate a regulated output signal based on a current reference signal and a voltage reference signal, wherein;
the output signal is applied to a load; and
the regulator controls at least one of the current reference signal and the voltage reference signal to control power loss within the power receiver.

Abstract
A power receiver for a wireless power transmission system that includes a power transmitter has input circuitry that converts power received from the power transmitter into an input signal. A regulator regulates the input signal to generate a regulated output signal based on a current reference signal and a voltage reference signal, and a load receives the regulated output signal. The regulator controls at least one of the current reference signal and the voltage reference signal to control power loss within the regulator. In one embodiment, the regulator globally controls the voltage of the rectified input signal and locally controls the current reference signal to limit power loss in the regulator as well as meet system load requirements.
