Abstract	The rapid growth of electric vehicles (EVs) necessitates efficient and reliable charging solutions. This study introduces an innovative LLC resonant DC-DC converter designed specifically for high-efficiency EV charging applications. Utilizing frequency modulation (FM) control strategy, the converter achieves superior performance in both steady-state and transient conditions across a wide range of input and output scenarios. Comparative analysis with conventional hard-switching DC-DC converters reveals the LLC resonant converter's advantages, including higher efficiency, reduced power dissipation, and improved electromagnetic interference (EMI) performance. Designed for domestic wall charging of electric motorcycles, this converter promises to enhance charging efficiency and reliability, contributing to the sustainable growth of the EV industry.
