하나의 양태는 무선 전력 송신기 (802) 를 제공한다. 무선 전력 송신기는 제 1 및 제 2 구성의 양자에서 무선 송신 전력을 위한 필드를 생성하도록 구성된 송신 안테나 (LI) 를 포함한다. 무선 전력 송신기는 제 1 커패시터 (CIA) 를 더 포함한다. 무선 전력 송신기는 제 1 및 제 2 구성 중의 하나에서 제 1 커패시터를 선택적으로 접속하도록 구성된 적어도 하나의 스위치 (SI, S2) 를 더 포함한다. 제 1 커패시터는 제 1 구성에서 송신 안테나와 직렬일 수 있고, 제 2 구성에서 송신 안테나와 병렬일 수 있다.
One aspect provides a wireless power transmitter. The wireless power transmitter includes a transmit antenna configured to generate a field for wireless transmit power in both a first and second configuration. The wireless power transmitter further includes a first capacitor. The wireless power transmitter further includes at least one switch configured to selectively connect the first capacitor in one of the first and second configuration, the first capacitor being in parallel with the transmit antenna in the first configuration and in series with the transmit antenna in the second configuration. The wireless power transmitter further includes a second capacitor in parallel with the transmit antenna and a transformer configured to operate at a first turns-ratio in the first configuration and a second turns-ratio in the second configuration, the first turns-ratio being lower than the second turns-ratio.
