摘要
通过对单相矩阵变换器原理图进行分析得到输出失真波形,进一步总结出波形失真的原因,提出改进思路及改进电路图,通过MATLAB仿真得到变换器理想的输出波形,并总结出该变换器具有输出频率连续可调、输入输出电流接近正弦波等优点,具有广阔的应用前景。
Obtain output wave shape based on the single-phase matrix converter principle,the output wave shape distortion reason was analyzed,the improvement mentality and the improvement circuit diagram was proposed.The single-phase matrix converter ideal output wave shape was obtained finally through the MATLAB modelling simulation.Through results,it was shown that this AC-AC converter had good features such a unlimted frequency,input and output electrical current approach sine wave etc,the developing foreground was very wide.
