摘要
传统空间矢量间接调制策略(Space Vector Indirect Modulation Strategy,简称SVIMS)下的矩阵变换器(MatrixConverter,简称MC)在非正常输入情况下,其性能会发生恶化。针对该现象,在简单介绍MC的SVIMS的基础上,分别采用PWM面积等效原理、传递矩阵和矢量内积3种方法,分析了MC输入电压中的非正常因素对MC输出电压的作用机理,揭示了非正常输入对SVIMS下MC性能影响的原因,为改善MC的性能奠定了基础。
The performance of matrix converter(MC) modulated by the conventional space vector indirect modulation strate-gy(SVIMS) under abnormal input condition is deteriorated.For this phenomenon,based on the SVIMS of MC,using PWM area equivalence principle,transfer matrix and vector inner-product methods,the effect mechanism of the abnormal compo-nents in the input voltage of MC to the output voltage is deeply analyzed,the cause of performance deterioration of MC under abnormal input is proposed.All the results presented afford the base for improving the performance of MC under the abnormal input condition.
