中文摘要

CLLLC型DC-DC变换器因其在双向功率传输中具备电压升降能力、全负载范围软开关及高效率特性,在V2G系统中备受关注。本文提出一种超局部无模型脉冲频率调制(PFM)控制策略,旨在解决传统PI控制在复杂工况下的动态响应与鲁棒性问题,提升变换器在双向运行时的控制性能。

English Abstract

CLLLC-type dc–dc converter (abbreviated as CLLLC converter) has drawn significant attention due to its capability to step-up and step-down voltage in both forward and reverse operation directions, while maintaining consistent operating characteristics, soft-switching across the full-load range, and high efficiency. Conventional control methods, such as proportional-integral regulator, are widely u...
