【摘要】 该文用Matlab Simulink 建立了空间矢量调制的矩阵变换器的2个仿真模型,1个简化模型,1个复杂模型。简化模型中,开关矩阵由9个理想开关组成, 不考虑任何换流引起的短路问题。在用于验证控制策略改进方法,试验外围电路参数及模型中模块的正确性时,简化模型可代替复杂模型。复杂模型主要用于模拟实际系统,用于检验在简化模型下已验证的策略或参数在实际条件下的工作情况。2个仿真模型的结果证明:矩阵式变换器的简化模型在验证功能上和实际模型能达到同样的效果,并能大大提高工作效率。2个仿真模型为矩阵变换器软、硬件的研究和调试带来极大方便。更多还原

【Abstract】 Two Matlab Simulation models: a simple model and a complex one, for the matrix converters with space-vector modulation are presented. In the simple model, switch matrix is composed of nine ideal switches. The simple model can be used to verify the improvement of the space-vector modulation strategy, to test the peripheral circuit parameters and to verify the validity of the modules. The complex model is used to simulate a practical system and to verify the going of the strategy or the parameters under the practical condition. The two simulation results reveal that the simple model is equal to the complex one on the function verification. The two models are greatly convenient to the research and the debug going of the MC software and hardware.更多还原
