摘　　要：针对某些特殊场合对变换器输出电压质量的严格要求,提出一种新型交错式三电平Cuk型变换器。采用一种新型交错对称式电路结构,不仅简单,而且兼具Cuk型电路和三电平电路的优势。设计变换器结构,分析变换器工作原理,推导输出电压表达式;针对变换器工作特性,进行参数设计和闭环控制器设计。同时,运用Saber仿真软件完成了仿真验证,证实了所设计变换器的正确性和可行性。A new type interleaved three level Cuk converter was proposed for some special occasions on the strict quality requirements of the converter output voltage. A new type of interleaved symmetric circuit structure was adopted by the converter,with simple circuit structure,it has the advantages of both Cuk circuit and three level circuit. The converter structure was designed,and then the working principle of the converter was analyzed. The expressions of the output voltage were derived,and the converter circuit parameters were designed based on the working characteristics. And the current and voltage instantaneous value controller was designed. After theoretical analysis,simulation was done using Saber simulation software,the correctness and feasibility of the converter were confirmed.
