Wireless Power Transfer Systems (WPTS) for electric vehicle charging require robust control to address misalignments and parameter variations. In this context, this paper proposes a comprehensive ninth-order dynamic analysis of Series-Series Wireless Power Transfer Systems (SS-WPTS), employing both Asymmetrical Clamped Mode (ACM) and Phase Shift (PS) modulation strategies. The analysis is validated through simulation and AC sweep results in two practical regimes using a 200 W SS-WPTS. PI controller gains are systematically determined in PLECS software using the AC sweep function to ensure robust performance, highlighting the critical role of adjusting switching frequency relative to resonance. Experimental validation on a 200 W prototype demonstrates that both control methods, when combined with PI regulation, achieve reliable voltage regulation, fast set-point tracking, and robust disturbance rejection under various scenarios. The system maintains stable operation despite variations in load, DC supply voltage, battery voltage, and misalignment. These results confirm the accuracy of the proposed model and dynamic analysis while highlighting the practical effectiveness of PI-controlled SS-WPTS in real-world charging scenarios.
