摘要: 本文用逻辑开关函数法,建立了具有离散采样和调制特性的变流器非线性系统理论模型. 此模型适用于整流器、逆变器、变频器等含晶闸管元件的非线性系统动态模拟、谐波计算和稳 定性研究.本文列举了此模型在变流器系统动态和谐波分析方面的应用结果.Abstract: 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.
