WIRELESS POWER TRANSFER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18288423 titled 'WIRELESS POWER TRANSFER
The abstract describes a patent application for a power transmitter that provides power to a power receiver through inductive power transfer and also enables communication between the two devices.
- The output circuit generates the power transfer signal in response to a drive signal from the driver.
- The communicator uses amplitude modulation to transmit messages to the power receiver and load modulation to receive messages from it.
- The controller controls the generation of the power transfer signal in a repeating time frame, alternating between power transfer intervals and communication intervals.
- The synchronizer manages the transmission and reception of messages between the power transmitter and receiver during specific time intervals.
Potential Applications: - Wireless charging systems for electronic devices - Communication systems for IoT devices - Power transfer and communication in industrial automation
Problems Solved: - Efficient power transfer without physical connections - Simultaneous power transfer and communication - Synchronization of communication between devices
Benefits: - Reduced need for cables and connectors - Enhanced convenience for charging and data transfer - Improved reliability and efficiency in power transmission
Commercial Applications: "Wireless Power and Communication System for IoT Devices: Revolutionizing Connectivity and Efficiency"

Original Abstract Submitted
A power transmitter () provides power to a power receiver () via an inductive power transfer signal. An output circuit () generates the power transfer signal in response to a drive signal generated by a driver (). A communicator () transmits messages to the power receiver () using amplitude modulation and receives messages from the power receiver () using load modulation. A controller () controls the driver () to generate the power transfer signal to apply a repeating time frame comprising a power transfer interval during which the power transfer signal is arranged to transfer power to the power receiver () and a communication time interval during which no power transfer signal is generated. A synchronizer () controls the power transmitter to transmit at least part of a first message from the power transmitter () to the power receiver () during a power transfer time interval and to receive a response message from the power receiver () during a communication time interval.
