COMMUNICATION IN A WIRELESS POWER TRANSFER SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18288203 titled 'COMMUNICATION IN A WIRELESS POWER TRANSFER SYSTEM

The power transfer system described in the abstract involves wirelessly providing power from a power transmitter to a power receiver using an inductive power transfer signal. Communication from the power receiver to the power transmitter is achieved through load modulation using the power transfer signal. This communication method utilizes chip sequences to represent symbols, with each symbol corresponding to a sequence of modulation load values.

The power transmitter includes a first communicator that correlates a received chip sequence from the power receiver with a set of reference chip sequences linked to data symbol values. By determining the data symbol based on the reference chip sequence with the highest correlation to the received chip sequence, data communication is established between the transmitter and receiver.

The system enables efficient and reliable power transfer while also facilitating data communication between the transmitter and receiver using load modulation techniques.

This innovation enhances the functionality of wireless power transfer systems by integrating data communication capabilities, expanding the potential applications of such systems.

By combining power transfer and data communication in a single system, this technology addresses the need for seamless integration of power delivery and data exchange in various applications.

The benefits of this technology include improved efficiency, reduced complexity, and enhanced versatility in wireless power transfer systems with integrated data communication capabilities.

Original Abstract Submitted

A power transfer system comprises a power transmitter () wirelessly providing power to a power receiver () via an inductive power transfer signal. Communication from power receiver () to the power transmitter () is by load modulation using the power transfer signal. The communication uses load modulation where each symbol is represented by a chip sequence being a sequence of modulation load values. The power transmitter () comprises a first communicator () which correlates a chip sequence received from the power receiver with a set of reference chip sequences being linked to data symbol values and determines the data symbol as the data symbol linked to a reference chip sequence for which the highest correlation with the first chip sequence is determined.
