| 分析了矩阵式变换器可等效为间接式交-直-交变换和采用输入双空间矢量调制的原理和具体实现方法。针对双空间矢量调制中传统算法在计算各矢量作用时间上存在误差的问题,提出了一种补偿算法。在一定程度上能够弥补因误差造成矢量作用时间缩短带来的实际空间矢量对参考空间矢量跟随性能下降的问题。算法简单可靠,对系统控制算法的复杂性不会增加很多,实用性强。在MATLAB的Simulink环境下对系统进行了建模仿真,仿真结果证明了补偿算法的有效性。 |

| This paper analyzes the principle and realization method for making the matrix converter equivalent to the indirect AC-DC-AC converter and for adopting the double space vector modulation. In view of calculation errors of vector action time which occur in the traditional algorithm in the double space vector modulation, it presents a new compensation algorithm which can compensate to some extent for the weakened tracking of the reference space vector by actual space vector due to shortened action time. The simple, reliable algorithm does not make the system control algorithm much more complex and is highly practical. System modeling is completed in the environment of MATLAB/Simulink, and the simulation results verify the effectiveness of the compensation algorithm. |
