摘要
分析了半桥LLC谐振变换器的工作原理,利用基波分析法对LLC谐振变换器进行了建模研究。在此基础上设计了一款微波加热用磁控管供电软开关电源,给出了主电路结构并设计了核心参数。提出了一种非常新颖的解决变压器偏磁饱和的解决方法。最后利用仿真软件SABER对所设计的电源进行仿真,验证了该款软开关电源设计方案理论分析的正确性。
The working principle of the half-bridge LLC resonant converter is analyzed. The first harmonic analysis method is used to study the modeling of the LLC resonant converter. On the bias of this, a soft switching power supply for microwave heating magnetron is designed. The main circuit structure is given and the core parameters are designed. Presents a very novel method to solve the transformer bias magnetic saturation solution. At last, the simulation software SABER is used to analyze the results of the LLC resonant soft switching power supply. And the theoretical analysis is verified by the simulation results.
