SYSTEMS AND METHODS FOR MEASURING POWER AND IMPEDANCE IN WIRELESS POWER CHARGING SYSTEMS |
摘要 |
A wireless power transmitter may generate a magnetic field via a transmit antenna to induce voltage in a receive antenna of a wireless power receiver to power the unit and/or charge the receiver's battery. An apparatus for measuring wireless power transfer at an operating frequency between the transmitter and the receiver is provided. The apparatus comprises a first clock configured to generate a first clock signal at a first clock frequency that is higher than the operating frequency of the wireless power transfer. The apparatus further comprises a controller configured to operate based on a second clock signal, the first clock frequency higher than a second clock frequency of the second clock signal. The controller is further configured to measure an amount of wireless power transfer based on the first clock signal. |
