Description:[001] The present invention pertains to the field of wireless power transmission and reception technologies. Specifically, it relates to a method and apparatus for controlling a wireless power receiver, wherein the receiver integrates a near field communication (NFC) antenna. This innovation aims to enhance the efficiency and functionality of wireless power systems by enabling concurrent communication and power transfer.
BACKGROUND OF THE INVENTION
[002] The field of wireless power transfer has seen significant advancements over recent years, driven by the increasing demand for convenient and efficient charging solutions for various electronic devices. Wireless power receivers, which enable the reception of energy transmitted wirelessly from a power source, are critical components in this technology. In parallel, Near Field Communication (NFC) technology has become integral for short-range data exchange and interaction between devices. The convergence of these technologies presents an opportunity to enhance both power reception and data communication in a single device.
[003] Currently, wireless power transfer systems operate through electromagnetic fields to transmit energy from a power transmitter to a receiver. This process allows for the elimination of physical connectors and cables, promoting user convenience and reducing wear and tear. However, the need for concurrent data communication capabilities within these systems remains largely unaddressed. NFC technology, known for its efficiency in facilitating short-range data transfers, offers a promising solution for integrating communication features into wireless power receivers.
[004] Several prior art solutions have attempted to address the integration of NFC technology with wireless power receivers. For instance, patents such as disclose methods for combining power transfer with data communication by incorporating NFC antennas within power receivers. While these approaches represent a step forward, they often encounter limitations related to interference between the power transfer and NFC functions. Additionally, these prior art solutions may suffer from inefficiencies in power transfer and communication, as well as increased complexity and cost in implementation.
[005] Another relevant prior art describes techniques for managing power and data transmission separately, employing distinct antennas and circuitry for each function. While this approach effectively separates power and data pathways, it fails to optimize the spatial and operational synergy between the power receiver and NFC components. The complexity of managing separate systems can lead to increased device size, reduced reliability, and higher manufacturing costs.
[006] Therefore, to overcome the shortcoming of the prior arts, there is a dire need to develop a wireless power receiver control method that integrates an NFC antenna within the same apparatus. This integration enables simultaneous power reception and data communication without significant interference between the two functions. By optimizing the design to ensure efficient operation and minimizing the impact of electromagnetic interference, the invention addresses the inefficiencies and complexities observed in prior art solutions. This approach not only enhances device functionality but also simplifies the overall system design, leading to improved performance and reduced costs.
SUMMARY OF THE PRESENT INVENTION
[007] The present invention provides a wireless power receiver control method that incorporates an integrated Near Field Communication (NFC) antenna within the receiver apparatus. This innovation enables concurrent wireless power reception and NFC-based data communication, facilitating a seamless and efficient interaction between the power receiver and external devices. The integrated NFC antenna is strategically designed to coexist with the power reception components, minimizing electromagnetic interference and optimizing the performance of both functions. This integration streamlines the device architecture, enhancing operational efficiency and user convenience by eliminating the need for separate communication systems.
[008] In addition to its integration benefits, the invention features a control method that intelligently manages the interaction between power transfer and NFC communication. By employing advanced signal processing techniques and optimized antenna design, the invention ensures that both power and data functions operate harmoniously, maintaining high levels of performance and reliability. The result is a compact, cost-effective solution that addresses the limitations of prior art, providing an improved wireless power receiver system with enhanced functionality and reduced complexity.

[014] Referring to Figure 1, the present invention relates to a novel method for controlling a wireless power receiver that integrates a Near Field Communication (NFC) antenna within the receiver apparatus. This detailed description outlines the innovative aspects of the invention, including its structural design, functional components, and operational mechanisms.
[015] The wireless power receiver of the present invention comprises a primary receiving coil for capturing electromagnetic energy transmitted from a power source and an integrated NFC antenna for facilitating near-field communication. The design incorporates the NFC antenna in proximity to the receiving coil, strategically positioning it to minimize mutual interference while optimizing signal reception for both power and data functions. The integrated system features a common housing that accommodates both the power receiving circuitry and NFC components, thereby reducing the overall footprint and simplifying device assembly.
[016] The core of the invention lies in its control method, which employs a sophisticated signal processing unit to manage the simultaneous operation of the power reception and NFC communication. The signal processing unit is equipped with algorithms designed to differentiate and prioritize the power and data signals, ensuring efficient operation without cross-interference. The method involves dynamically adjusting the operating parameters of the power receiver and NFC antenna based on real-time conditions, such as the distance between the NFC-enabled device and the receiver or variations in power levels.
[017] During operation, the power receiver captures energy transmitted wirelessly through the primary receiving coil, converting it into usable electrical power. Concurrently, the integrated NFC antenna communicates with external NFC-enabled devices to exchange data, such as device authentication information or configuration settings. The signal processing unit regulates the power reception and NFC communication by selectively filtering and amplifying the received signals, thereby enhancing overall system performance. The control method includes feedback mechanisms that adjust the operational parameters in response to changes in the external environment or device status, optimizing both power transfer efficiency and data communication reliability.
