摘　　要：LLC谐振变换器并联使用时,为实现变换器之间的输出均流,通常引入移相控制。重点分析LLC谐振变换器的移相特性,首先基于LLC谐振变换器的基波模型推导移相角度与参数误差的关系,然后讨论了增益和相移特性,并与实验结果进行比较。为LLC谐振变换器并联的参数和移相控制设计提供指导。When the LLC resonant converters are used in parallel,in order to achieve output current sharing between converters ,phase shift control is typically introduced.This paper focuses on the characteristic of phase shift control of LLC resonant converter,firstly, deduces the relationship between phase shift angle and parameter mismatch based on fundamental model of LLC resonant converter, then discusses the characteristic between gain and phase shift, and compares with experimental resuhs.It provides guidance for the design of parameter and phase shift control of parallel LLC resonant converter.
