摘要
在非正常输入条件下,常规的空间矢量间接调制方法会引起矩阵变换器的性能恶化。针对这一问题,提出一种矩阵变换器空间矢量间接调制改进方法。该方法利用矢量方法构造一个全新的修正系数,并利用该修正系数实现对常规空间矢量间接调制方法的改进,使得修正后的空间矢量间接调制方法调制的矩阵变换器即使在非正常输入条件下仍能获得良好的性能。仿真和试验结果均表明了方法的有效性。
The performance of matrix converters(MCs) modulated by the conventional space vector indirect modulation(SVIM) method under abnormal input condition will deteriorate.For this phenomenon,an improvement method for the SVIM of MC was proposed.It realizes the improvement of the conventional SVIM by a new correcting factor constructed by a vector method,such that well performance of MCs modulated by the improved SVIM can be obtained under the abnormal input condition.The results of the simulation and the experiment both show the effectiveness of the improvement method.
