Wireless Power Transfer Efficiency Optimization Tracking Method based on Full Current Mode Impedance Matching

Abstract Wireless power transfer (WPT) technology is a contactless wireless energy transfer method with wide-ranging applications in fields such as smart homes, the Internet of Things (IoT), and electric vehicles. Achieving optimal efficiency in wireless power transfer systems has been a key research focus. In this paper, we propose a tracking method based on full current mode impedance matching for optimizing the efficiency of wireless power transfer. This method enables efficiency tracking in WPT systems and allows seamless switching between continuous conduction mode and discontinuous mode, expanding the efficiency detection capabilities of the wireless power transfer system. The proposed method is simulated in the MATLAB software environment to validate its feasibility and effectiveness. The simulation results demonstrate that the proposed method enables optimal efficiency tracking in wireless power transfer systems while extending the detection capabilities, thereby offering practical value and potential for widespread application.
