摘要
矩阵式变换器工作时存在大量谐波,为分析产生的谐波,以间接空间矢量调制法为例,简要叙述了矩阵式变换器空间矢量调制策略的基本原理。在此基础上,首次提出"扇区谐波"的概念,给出其基波分量的数学表示式,并对空间矢量调制策略带来的这种特有谐波作了量化分析,给出数值计算的结果和它的性质。并在Matlab/Simulink中进行建模和仿真,验证了分析结果的正确性。
To analyse the harmonic produced by matrix converter, taking the indirect space vector modulation as on example,the basic principIe of space vector modulation strategy for matrix converter is briefly presented in the paper. Based on that,the concept of ＂sector harmonic＂is proposed for the first time. The formula of first order sector harmonic is deduced. Such special harmomic brought in the the space vector modulation strategy is quantitatively analyzed and the calculation results and it＇s features are presented. To verify the conclusion, the modeling and simulation of matrix converter are built in Matlab/Simulink.
