摘　　要：选取移相全桥ZVZCS DC/DC变换器,分析所选拓扑的工作过程、设计关键参数,用Saber软件对软开关电路进行仿真,验证设计的正确性,并充分反映拓扑结构的高效特性,为实际电路的研究提供依据。同时,针对移相全桥DC/DC变换器这种强非线性系统,提出模糊自适应分数阶PI^(λ)D^(μ)先进控制算法,用Saber与Matlab软件协同仿真的方式进行变换器闭环仿真,结果表明:相较于传统PID,模糊自适应分数阶PI^(λ)D^(μ)先进控制算法的动态性能更佳。In this paper,a phase-shifted fl-bridge ZVZCS DC/DC converter was selected,and the work-ing process of the selected topology was analyzed and its key parameters were designed,including having Saber software adopted to simulate soft switching circuit and verify correctness of the design and fully reflect high-efficiency characteristics of the topology,as well as provide a basis for the research of actual circuits.In addition,as for strong nonlinear system of the phase-shifted full-bridge DC/DC converter,a fuzzy adap-tive fractional order PI^(λ)D^(μ) advanced control algorithm was proposed.The closed-loop simulation of the con-verter completed by co-simulation of Saber and Matlab software show that,compared with the traditional phase-shifted full-bridge ZVZCS converter based on PID control,the dynamic performance of fuzzy adaptive fractional PI^(λ)D^(μ)advanced algorithrn is better.
