Dual-Input Single-Output DC-DC Conversion for Common-Mode Current Suppression in Misaligned Resonant Capacitive Power Transfer Systems

Abstract

A dual-input single-output DC-DC is proposed to reduce common-mode currents in laterally misaligned resonant capacitive power transfer systems, thereby mitigating shield voltage rise and electromagnetic emissions without compromising power sharing or efficiency. Simulations and experimental results validate its performance over a misalignment range of ±50% of the transmission distance. Future work will involve fine-tuning the experimental system and exploring the impact on inverter performance.
