| 摘 要： | 为各种开关结构的直流功率变换器提出一种新的、统一的建模方法，该法的基本途径是：将变换器中的全部时变开关集中在一个子网络里，用时间平均技术及脉冲响应法，导出开关子网络的低频效模型，与变换器的其它部分连结起来，构成了可用ＳＰＩＣＥ作辅助分析的全等电路，该方法能够在计算机辅助下，对开关变换器作瞬态分析、输入－输出传递函数的频响分析（纹波抑制特性）、控制信号占空比与输出的交流分析。给出了分析实例。

| Abstract: | A novel approach of modelling a switched DC-DC converter is presented. This method is very simple and suitable for simulation with program SPICE. The basic procedure of modelling is consentrating swithes in a subnetwork, finding its equivalent model, combining the subnetwork model and other elements of the converter, then a total equivalent circuit results.With the help of this method, we can realize the computer aided analysis of converters, such as input-output transfer function (ripple passing) and pulse- wide- variant transfer function (control sensitivity). Illustrated example is provided. |
