Dynamic Matching Circuit for Wireless Charging Standards

The patent implements a dynamic matching circuit that can switch between different matching configurations based on the detected wireless charging standard. The circuit uses a control unit to dynamically adjust matching components (such as capacitors or inductors) to optimize performance for either WPC or PMA standards, resolving the contradiction between fixed-configuration efficiency and multi-standard compatibility.

The patent designs a universal matching circuit that incorporates multiple matching configurations within a single circuit architecture. By integrating both WPC and PMA matching circuits with a switching mechanism, the system achieves multi-functionality, allowing it to adapt to different standards while maintaining optimized charging efficiency for each standard through selective activation of the appropriate matching configuration.

The patent merges multiple matching circuits into a single integrated matching module with a unified control architecture. Instead of providing completely separate WPC and PMA matching circuits, the design combines them into one module that shares common components (such as the receiving coil and control unit), reducing overall device complexity while maintaining compatibility with both standards through selective activation.

The patent uses dynamic switching mechanisms to activate only the required matching circuit configuration based on the detected standard. This dynamic approach allows the system to maintain both WPC and PMA matching capabilities without permanently connecting all components, thereby reducing circuit complexity while preserving full compatibility with both standards.

The patent implements a dynamically adjustable matching circuit that can reconfigure its parameters based on the active wireless charging standard. The control unit detects the standard (WPC or PMA) and adjusts the matching circuit's components (such as variable capacitors or inductors) to optimize performance for the current standard, thereby maintaining high charging efficiency while using a single unified circuit architecture.

The patent changes the electrical parameters of the matching circuit dynamically based on the operating standard. By adjusting parameters such as capacitance, inductance, or resonant frequency according to the detected standard, the single matching circuit achieves optimized performance for both WPC and PMA without requiring separate dedicated circuits, thus resolving the contradiction between simplicity and efficiency.
