This paper proposes a synchronous rectification strategy with enhanced robustness to address closed-loop instability in magnetically coupled wireless power transfer (MC-WPT) systems. A strobe mapping model for an LCC-S resonant network MC-WPT system is established, and the soft-switching conditions for synchronous rectification are analyzed. Based on the Jacobian matrix, a stability criterion for closed-loop controlled synchronous rectification is derived. Simulation results verify the strategy’s effectiveness, demonstrating stable full-load-range operation while achieving zero-voltage switching (ZVS) at the rectifier. And the MC-WPT system using the strategy proposed in this paper has achieved stable transmission in the power range of 86.86 W to 1.07 kW.

摘要

This paper proposes a synchronous rectification strategy with enhanced robustness to address closed-loop instability in magnetically coupled wireless power transfer (MC-WPT) systems. A strobe mapping model for an LCC-S resonant network MC-WPT system is established, and the soft-switching conditions for synchronous rectification are analyzed. Based on the Jacobian matrix, a stability criterion for closed-loop controlled synchronous rectification is derived. Simulation results verify the strategy’s effectiveness, demonstrating stable full-load-range operation while achieving zero-voltage switching (ZVS) at the rectifier. And the MC-WPT system using the strategy proposed in this paper has achieved stable transmission in the power range of 86.86 W to 1.07 kW.
