DEVICE AND METHOD PROVIDING FEEDBACK IN WIRELESS POWER TRANSFER - A simplified explanation of the abstract
- This abstract for appeared for patent application number 18126657 Titled 'DEVICE AND METHOD PROVIDING FEEDBACK IN WIRELESS POWER TRANSFER'
Simplified Explanation
The abstract describes a system where a first device can wirelessly receive power from a second device. The second device has a resonance circuit with a specific frequency. The first device has its own resonance circuit with the same frequency, a capacitor connected to the resonance circuit, a rectifier to convert the alternating current (AC) voltage at the resonance frequency, and a control circuit connected to the capacitor. The control circuit determines a specific period based on feedback information to be sent to the second device. During normal operation, the control circuit applies a first voltage and then a higher second voltage to the capacitor for this specific period.
Original Abstract Submitted
A first device wirelessly receives power from a second device including a second resonance circuit having a resonance frequency. The first device includes: a first resonance circuit having the resonance frequency, a first capacitor connected to the first resonance circuit at a first node, a rectifier configured to rectify an alternating current (AC) voltage apparent at a first node and oscillating at the resonance frequency, and a control circuit connected to the first capacitor, and configured to determine a first period based on feedback information to be provided to the second device, and alternately apply a first voltage and a second voltage higher than the first voltage to the first capacitor for the first period during a normal output mode.
