Simulation research of voltage source rectifier based on switching function

通过对三相电压型整流器双环控制算法的分析,建立基于开关函数的主电路拓扑、双环控制结构和系统的MATLAB仿真模型,并对系统的稳态和动态性能进行了仿真研究。仿真结果证明了系统模型的正确性,同时,也表明了基于开关函数的MATLAB仿真模型克服了采用其它仿真软件和方法仿真电压型整流器时的缺点和不足。

By analyzing the double-loop control algorithm of three-phase voltage source rectifier, the main circuit topology, double-loop control configuration and system of MATLAB are modeled, The static and dynamic performance of the system are also simulated. The results of simulation verify the correctness of this model, At the same time, these indicate that the disadvantages and shortcomings when the voltage source rectifier is simulated by other simulation tools or methods can be overcome by the model of MATLAB based on switching function.
