| 摘 要： | 应用傅里叶变换对含有多相开关、周期性动作的线性开关网络进行分析。基于双图修改的结点法建立了多相开关网络时域方程的通式,应用傅里叶变换求出各相响应的频谱函数并叠加求得完全响应。最后给出计算实例,并与已发表的结果加以比较。与其它方法不同,文章旨在寻求一种同时适用于理想开关电容网络和一般多相周期开关线性网络的统一方法。

| Abstract: | A method for analysis of multiphase periodically switched linear networks is given by using Fourier transform.The network equations based on the two-graph modified nodal analysis are formulated initially in the time domain. Then the Fourier transform is applied to these equations and complete response of the network is computed. Finally, the theoretical results presented in the paper are applied to the example of a switched network. The presented theory unifies the analysis of ideal switched capacitor circuits with that of the general periodically switched linear network. |
