Modelling of Nonlinear System with Discrete-Sampling and Modulation Characteristics
具有离散采样和调制特性的非线性系统建模

By using the Logic-Switching Function method, a theoretical model of the nonlinear converter system with discrete-sampling and modulation characteristics is established in this paper. This model can be used for the dynamic simulation, harmonic computation and stability study of the nonlinear systems containing thyristoreelements, such as converter, inverter and cycloconverter. Some practical results of this model for the dynamic and harmonic analysis of converter system are presented.
