ADAPTIVE WIRELESS ENERGY TRANSFER SYSTEM

摘要

Exemplary embodiments are directed to wireless power transfer using magnetic resonance in a coupling mode region between a charging base (CB) and a remote system such as a battery electric vehicle (BEV). The wireless power transfer can occur from the CB to the remote system and from the remote system to the CB. Load adaptation and power control methods can be employed to adjust the amount of power transferred over the wireless power link, while maintaining transfer efficiency.

主权项

1. An apparatus for wirelessly transmitting power, the apparatus comprising:
a power conversion circuit configured to convert power received from a power supply and operate in at least one of a first mode and a second mode; a first power transfer component electrically coupled to the power conversion circuit, the first power transfer component configured to wirelessly transfer charging power to a second power transfer component at a receiver based at least in part on the converted power; and a controller configured to reconfigure the power conversion circuit between at least the first and second modes based at least in part on a value indicative of a degree of coupling between the first and second power transfer components.
