开关电源SMPS（switch mode power supply）中的DC-DC变换器是影响装置体积质量和工作效率的核心。LLC谐振变换器作为经典的DC-DC拓扑结构，其运用软开关技术和磁集成技术，具有高效率、高功率密度及抑制谐波等特点。从变压器绕组结构方案和控制拓扑优化方案出发，综述了应用于开关电源中的LLC谐振变换器的优化方法研究现状，并针对同步整流和APR（all-primary-referred）磁集成模型下平面变压器对电路的影响提出自身见解，最后依据第三代宽禁带材料及电磁兼容性进行优化方法的展望。

The DC-DC converter in a switch mode power supply (SMPS) is the core part that affects the device's volume, weight and working efficiency. As a classic DC-DC topology, the LLC resonant converter uses the soft switching technology and magnetic integration technology, which has characteristics such as a high efficiency, a high power density and harmonics suppression. The research status of optimization methods for LLC resonant converters applied in SMPS is reviewed, starting from the transformer winding structure schemes and control topology optimization schemes. In addition, suggestions on the effects of synchronous rectification and the planar transformers under an all-primary-referred (APR) magnetic integration model on the circuit are given. Finally, the optimization methods based on the third-generation wide bandgap material and electromagnetic compatibility are prospected.

Key words
