Abstract

This paper proposes an improved PI control strategy for series-compensated wireless power transfer (WPT) systems to achieve robust constant-voltage (CV) and constant-current (CC) outputs under dynamic load conditions. The control framework incorporates a frequency-domain optimization algorithm to mitigate integral windup during load transitions. Simulation results under 5Ω to 10Ω load steps demonstrate the system maintains CV error ≤ ± 0.2% and CC error ≤ ± 0.4%, with dynamic recovery times reduced by 40% compared to traditional PI control. The proposed method addresses two critical limitations of conventional PI control: fixed parameters struggling to handle nonlinearities and integral windup causing overshoot. By integrating stability criterion-based parameter adjustment and load dynamics characterization, the strategy achieves adaptive regulation for SS-WPT systems. The SS topology’s inherent voltage regulation capability is leveraged, offering simplified parameter design and low-order system modeling advantages. This work contributes to the practical implementation of WPT in applications requiring stable energy delivery, such as electric vehicle charging and industrial automation. Future research will focus on experimental validation and extending the framework to include mutual inductance adaptation for dynamic charging scenarios.
