Abstract

Due to fast fluctuating input voltage, dynamic wireless charging requires a post-regulator stage for battery charging control and management. This regulator stage has a high requirement on efficiency, size as well as control performance to ensure tight regulation and fast trainset. This paper addresses the control challenges by modeling the system and designing the compensator with input voltage feedforward control. In addition, high resolution PWM is implemented to improve transient performance and current balancing among the phases. Experimental results prove the effectiveness of the proposed schemes and validates 180 kW closed-loop 4-phase operation at 99% efficiency.
