TUNING CIRCUIT AND METHOD FOR WIRELESS POWER TRANSFER SYSTEMS |
摘要 |
This disclosure provides systems, methods and apparatus for wireless power transfer and particularly wireless power transfer to remote systems such as electric vehicles. In one aspect, a wireless power transfer system includes a transmitter and a receiver. The transmitter includes a first inductive element and a current generator. The current generator supplies a current to the first inductive element to generate an electromagnetic field. The receiver includes a second inductive element, a tuning circuit, and a controller. The second inductive element receives wireless power from the electromagnetic field. The tuning circuit has a reactance and includes a plurality of capacitive elements connected to the second inductive element. The plurality of capacitive elements supply an output current to a load. The controller selectively connects the plurality of capacitive elements in a plurality of configurations. The tuning circuit has substantially the same reactance in each of the plurality of configurations. |
