摘要

本研究提出了一种高效、隔离、LLC谐振的电动汽车充电DC-DC变换器，采用调频(FM)控制策略。分析了该变换器在多种输入输出条件下的稳态和暂态性能。对传统硬开关DC-DC变换器和谐振DC-DC变换器进行了性能对比分析。该LLC谐振DC-DC变换器具有更高的效率、更低的功耗和更好的电磁干扰性能。本文设计的LLC谐振变换器是针对家用电动摩托车的壁式充电应用而设计的。

Design of LLC Resonant Converter for High Efficiency EV Charging

This study presents a highly efficient, isolated, LLC resonant DC-DC converter for electric vehicle charging, using the control strategy namely Frequency Modulation (FM). The steady state and transient state performance of the converter under a wide range of input and output conditions was analyzed. A comparative performance analysis of the conventional hard switching DC-DC converter and the resonant DC-DC converter was conducted. The LLC resonant DC-DC converter gave promising results in terms of higher efficiency, lower power dissipation and better EMI performance. The LLC resonant converter presented in this work is designed for wall charging application of an electric motorcycle in a domestic environment.
