Efficient Wireless Power Transfer System (WPTS) necessitates precise alignment between primary and secondary coils, which can be challenging due to misalignments and parameter variations. This paper presents a dynamic analysis of Series-Series Wireless Power Transfer Systems (SS-WPTS), focusing on the impact of switching control techniques on system performance. Specifically, a 9th-order dynamic analysis of SSWPTS using Asymmetrical Clamped Mode (ACM) control is proposed, with a comparison to Phase Shift (PS) control. Simulation and AC sweep results of 500W SS-WPTS are investigated in two case scenarios to validate the analysis. Through simulations and AC sweep in PLECS software, PI controller gains are determined to achieve robust performance and emphasize the importance of changing switching over resonance frequency to maintain better efficiency with varying switching techniques.
