WIRELESS POWER TRANSFER RECEIVER HAVING CLOSED LOOP VOLTAGE CONTROL |
| 摘要 |
An apparatus for wirelessly receiving power via a wireless field generated by a transmitter includes a resonator configured to generate electrical current to power or charge a load based on a voltage induced in the resonator in response to the wireless field, a first variable capacitor electrically coupled to the resonator and configured to adjust a first capacitance of the first variable capacitor responsive to a first control signal, a second variable capacitor electrically coupled to the resonator and configured to adjust a second capacitance of the second variable capacitor responsive to a second control signal, and a control circuit configured to adjust and apply the first control signal and the second control signal to the first variable capacitor and the second variable capacitor, respectively, to adjust a resonant frequency of the resonator and a voltage output to the load based on an electrical characteristic indicative of a level of power output to the load. |

1. An apparatus for wirelessly receiving power via a wireless field generated by a transmitter, the apparatus comprising:
a resonator configured to generate electrical current to power or charge a load based on a voltage induced in the resonator in response to the wireless field; a first variable capacitor electrically coupled to the resonator and configured to adjust a first capacitance of the first variable capacitor responsive to a first control signal; a second variable capacitor electrically coupled to the resonator and configured to adjust a second capacitance of the second variable capacitor responsive to a second control signal; and a control circuit configured to adjust and apply the first control signal and the second control signal to the first variable capacitor and the second variable capacitor, respectively, to adjust a resonant frequency of the resonator and a voltage output to the load based on an electrical characteristic indicative of a level of power output to the load. |
