Abstract

In this paper, a modified switching algorithm for open end winding induction motor drive with less number of switching states is implemented. Open end winding induction motor requires two voltage sources operating in dual mode. With the help of two inverters, it generates 18 active voltage space vectors and three-level output voltage. The proposed algorithm is implemented to operate the induction motor drive only with two-level output voltage. Hence, the proposed algorithm is implemented only with 6 active voltage vectors and 2 null vectors. By using the proposed algorithm the induction motor drive is operated with two-level voltage and requires 8 switching states, so it provides higher switching states redundancy. The effectiveness of proposed algorithm verified experimentally with dspace DS-1104 and it is interfaced through MATLAB/simulink RTI-model.
开放式绕组异步电动机直接转矩控制的实验实现
本文提出了一种改进的少开关状态的开端绕组异步电动机驱动开关算法。开放式绕组感应电动机需要两个电压源在双模式下工作。在两个逆变器的帮助下,产生18个有源电压空间矢量和三个电平的输出电压。该算法实现了感应电机驱动仅在双电平输出电压下运行。因此,该算法仅使用6个有源电压矢量和2个零矢量实现。采用该算法,感应电机驱动采用双电平电压运行,需要8个开关状态,具有较高的开关状态冗余性。通过dspace DS-1104实验验证了该算法的有效性,并通过MATLAB/simulink rti模型进行了接口。
