ELECTRONIC DEVICE FOR WIRELESSLY RECEIVING POWER AND METHOD OF OPERATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18343511 titled 'ELECTRONIC DEVICE FOR WIRELESSLY RECEIVING POWER AND METHOD OF OPERATING THE SAME
Simplified Explanation
The abstract describes an electronic device that wirelessly receives power from an external device. The device includes a power reception circuit, an impedance compensation circuit, a rectifier circuit, a battery, and a control circuit. The control circuit is responsible for rectifying the received power into direct current (DC) power, identifying the voltage or current of the rectified power, determining the duty cycle of a control signal to control the impedance compensation circuit, and adjusting the voltage output of the impedance compensation circuit based on the duty cycle.
- The electronic device wirelessly receives power from an external device.
- The power reception circuit includes a coil to capture the wireless power.
- The impedance compensation circuit is connected to the power reception circuit and compensates for any impedance mismatch.
- The rectifier circuit converts the received power into DC power.
- The battery stores the rectified power for later use.
- The control circuit controls the rectifier circuit, identifies the voltage or current of the rectified power, determines the duty cycle of a control signal, and adjusts the voltage output of the impedance compensation circuit.
Potential Applications
- Wireless charging of electronic devices such as smartphones, tablets, and wearables.
- Powering IoT devices without the need for physical connections.
- Charging electric vehicles wirelessly.
Problems Solved
- Eliminates the need for physical connections or cables for charging.
