摘要

本文介绍了在Matlab&Simulink中对矩阵变换器进行数学建模和分析的工作。矩阵变换器用于直接交流-交流功率转换。所使用的开关的门信号是由最优幅度文丘里尼调制技术(OVAM)产生的。在不考虑负荷位移系数的情况下，该方法得到的最大电压传递比为0.866。采用鼠笼式三相异步电动机模型作为负载进行仿真。对仿真结果进行了分析。实验结果证明了矩阵变换器变换频率的有效性。

Mathematical Modelling of Matrix Converter

This paper describes the work carried out to mathematically model and analyse matrix converter in Matlab&Simulink. Matrix converters are used for direct AC-AC power conversion. The gate signals for the switches used are generated with Optimum Amplitude Venturini Modulation Technique (OVAM). The maximum voltage transfer ratio obtained with this method is 0.866 with a unity displacement factor regardless of the load displacement factor. A model of three phase squirrel cage induction motor is used as a load for simulation. The simulation results are analyzed. The results prove the effectiveness of the matrix converter for changing frequency.
