摘要
介绍了矩阵变换器(MC)的优点,在此基础上分析单相矩阵变换器的工作原理、拓扑结构及推导过程,并基于Simulink进行仿真研究.以此来证明这种变换器的优点.通过仿真结果,发现这种交-交变换器具有输出频率连续可调、输出电压波形存在畸变,但在一定范围内连续可调、输入输出电流较接近正弦波等优点,发展前景大,值得进一步研究.
The merits of matrix converter is presented in this paper.The principal,topology and the process of deduction of single-phase MC are analysed.The simulation results based on Simulink are also given,which testify this converter merits.Through simulink results,it is shown that this AC-AC converter has good features such as unlimted output frequency,variable voltage in an limted range,in despite of output voltage wave being aberrance,input and output electrical current approach sine wave etc,the developing foreground is wide and it is deserved to further research.
