摘　　要：基于单相矩阵变换器原理图得到产生畸变的输出波形,并进一步分析了输出波形畸变的原因,提出了改进思路以及改进电路图,最终通过Simulink的建模仿真得到了单相矩阵变换器理想的输出波形,并发现这种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,发展前景大,值得进一步研究.The output wave shape is obtained based on the single-phase matrix converter principle. Reasons of the output wave shape distortion are analyzed. The improving methods and the improving circuit diagram are proposed. Finally the output wave shape of single-phase matrix converter ideal is obtained by the simulink modeling simulation. It is shown that the AC-AC converter has good features such as unlimited output frequency, input and output electrical current approach sine wave etc. With good developing foreground, it deserves further researching.
