Application of Space Vector Theory in Three Phase Pulse Converter

将空间向量理论引入到三相理想脉冲变流器中 ,从而在很大程度上减少了计算量 .通过旋转坐标变换和状态空间描述得出结构不同的 2种仿真模型 ,然后在Matlab/Simulink环境下对 2种模型结构进行了仿真 .分析仿真结果可知 ,线性化处理后的简化模型与精确模型的分析结果非常一致 ,基本上反映了实际结果 ,并在模型上得到了很大的简化 ,给仿真带来了方便 .

Space vector theory is applied to three-phase pulse converter,thus to simplify the computation on a large extent.By introducing rotation axis conversion and state space description into the converter,two kinds of model structures are presented in the article and then simulated based on Matlab/Simulink.By analyzing the result of simulation,the simulation result of lined model approaches to the result of the precise model as well as the practical one thus simplifying the simulation model.
