POWER RECEPTION DEVICE AND METHOD FOR CONTROLLING CHARGING OF POWER RECEPTION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17854754 titled 'POWER RECEPTION DEVICE AND METHOD FOR CONTROLLING CHARGING OF POWER RECEPTION DEVICE
Simplified Explanation
The patent application describes a power reception device that can receive power wirelessly and convert it into usable DC power. The device includes a power reception circuit, a communication circuit, a modulation depth monitoring circuit, and a processor.
- The power reception circuit consists of a receive circuit with a coil and a first capacitor, and a rectifier circuit that converts the received power into DC power.
- The communication circuit includes multiple detuning switching circuitries, each with a second capacitor and a switch, which can change the voltage of the power received in the coil. It also has a modulation circuit that can turn the switch on or off based on a control signal from the processor.
- The modulation depth monitoring circuit measures the voltage of the rectified DC power and provides the modulation depth information to the processor.
- The processor uses the modulation depth information to identify a detuning switching circuitry for data modulation. It controls the modulation circuit to modulate data using the identified circuitry and limits the modulation depth within a specified range.

Original Abstract Submitted
A power reception device is provided. The power reception device includes a power reception circuity, a communication circuit, a modulation depth monitoring circuit, and a processor electrically connected with the power reception circuity, the communication circuit, and the modulation depth monitoring circuit. The power reception circuity includes a receive circuit that receives power from a wireless power transmitter and includes a coil and a first capacitor and a rectifier circuit that rectifies the power received by the receive circuit to convert the power into dual connectivity (DC) power. The communication circuit includes a plurality of detuning switching circuitries, each of which includes a second capacitor and a switch and changes a voltage of the power received in the coil and a modulation circuit that turns on or off the switch based on a control signal received from the processor. The modulation depth monitoring circuit monitors a voltage of the rectified DC power to measure a modulation depth and provides the processor with the modulation depth. The processor identifies a detuning switching circuity to perform data modulation among the plurality of detuning switching circuitries based on the modulation depth, controls the modulation circuit such that data is modulated by means of the identified detuning switching circuity and limits the modulation depth such that the modulation depth belongs to a specified range, and controls the modulation circuit based on the data to be transmitted to the wireless power transmitter.
