| 摘 要： | 该文详细分析了电压反馈型零电流开关Boost变换器的工作过程，建立了变换器工作在不连续运行模式(DCM)下的精确离散映射，对此数学模型进行了稳定性分析，确定了变换器中元件参数与其分岔稳定性的关系，在此基础上准确计算出了系统稳定运行的典型参数范围，利用Natlab6．5软件中的电力系统仿真模块(SimPowerSystems)对电路进行仿真分析，针对ZCS Boost变换器的特点建立仿真模型，并在Matlab／Simulink软件包环境下对该模型进行模拟仿真，得到了满意的结果，与理论分析取得一致。

| Abstract: | The working procession of the ZCS Boost converter is analyzed, and the discrete mapping of the converter which is operated under the discontinuous mode is proposed in this artical. Based on this model, the stabilization analysis is carried out, the relationship of some critical parameters and the stability of the boost converter is available. Through simulating integrating Matlab/Simulink (SimPowerSystems)software, simulation modeling is setup and the satisfatory results confirms the the theoretical analysis. |
