  • Dynamic wireless charging (DWC) technology holds promise in addressing range anxiety by providing continuous charging for electric vehicles in motion. However, challenges arise from output fluctuations due to variations in mutual coupling caused by vehicle movement, impacting battery lifespan and system efficiency. This paper introduces a novel integral terminal sliding mode-based proportional-integral (PI) control scheme to mitigate output voltage fluctuations in dynamic wireless charging systems. The proposed control strategy ensures a stable output voltage despite mutual coupling variations caused by receiver movement, with minimal ± 0.25% and ± 0.5% ripple at speeds of 50 km/h and 100 km/h, respectively. Notably, this control strategy offers fast convergence, superior transient performance, and high robustness. The detailed design procedure of the proposed controller is outlined, and simulation results demonstrate its effectiveness in suppressing voltage ripple.
