摘　　要：针对改进型三电平Buck直流变换器这种高阶、离散、非线性、时变的系统,分析了其工作模态和工作原理。利用状态空间平均法,结合欧拉公式,建立了其数学模型,并按照其数学模型组建了闭环控制系统。实验结果表明,其数学模型具有一定的合理性。The work mulfi-modalities and principle of an improved three level Buck DC-DC converter are analyzed,which is a dynamic system characterized by high-order,discrete,nonlinear and time-varying.The mathematical models were set up with average state space method and euler formula.The closed control system was built with mathematical models.The experimental results show the models are rationality.
