摘　　要：LLC型串并联谐振变换器具有较高的转换效率,根据电路直流增益特性、谐振部分阻抗特性及软开关实现条件,分析推导了主要参数设计方法。结合ST公司推出的L6599集成芯片的特点和主要功能,并给出外围控制电路设计。最后设计完成样机一台,测试结果和实验数据证明了设计的可行性。LLC series-parallel resonant converter has comparatively higher efficiency. In this paper, we deduce the main parameters on the basis of our analysis on DC voltage gain characteristics, input independence feature and the qualification of achieving zero-voltage or zero-current switching. With the L6599 chip produced by ST Company, we deign the peripheral circuits and finally realize a sample converter. The testing results verify our design.
