WIRELESS POWER TRANSMISSION DEVICE AND OPERATING METHOD OF WIRELESS POWER TRANSMITTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17982855 titled 'WIRELESS POWER TRANSMISSION DEVICE AND OPERATING METHOD OF WIRELESS POWER TRANSMITTER
Simplified Explanation
The abstract describes a wireless power transmission device that includes a converter circuit, a resonant tank, a current sensing circuit, and a controller. The device generates a test signal based on an input current, which is used to transmit wireless power through the resonant tank. The current sensing circuit detects the input current during wireless power transmission. The controller controls the converter circuit to generate the test signal, calculate the quality factor of the resonant tank based on the sensed input current, and reset the test frequency according to a comparison with a stored reference quality factor. The controller can also reset the test frequency or transmit a digital ping signal to the wireless power reception device based on the quality factor comparison.
