摘要
详细介绍了矩阵变换器的拓扑结构及工作原理,并讨论了矩阵变换器的开关函数调制方法和空间矢量调制方法。最后对基于上述两种调制策略的矩阵变换器进行仿真。由结果可知:采用空间矢量调制时电机启动较快,低频和高频时电机的运行性能也好于开关函数调制,但采用开关函数调制时,电机的定子电流谐波特性好于空间矢量调制所得到的结果。
This paper introduces the topology and working principle of matrix converter in detail,and discusses the switching function modulation method and space vector modulation method of matrix converter.Finally,the matrix converter with two modulation strategies is simulated.The results show that:when space vector modulation is used,the motor starts up faster,and its performance is better than switching function modulation at low frequency and high frequency.However,when switching function modulation is used,the harmonic characteristics of stator current of the motor are better than the results obtained by space vector modulation.
