Svm Algorithm In The Exchange Control System Applications

The system that this paper introduces has mainly completed the SVM arithmetic realized by the DSP TMS320LF2402 and the application in the AC frequency conversion system.At first, the foreword of this paper has done a detailed introduction about the development of the whole AC timing system. And then a brief introduction about the researching background of the tasks is given. In the end, the researching contents and the personal tasks of the problem are put forward.Afterward, a summary including the technique target, the project introduction and the whole frame of the project about the system is given in the second chapter. In the third chapter, it has particularly introduced the theory of the SVM arithmetic and some key techniques used in the system-the resolution of the PWM mode distortion, the dead-time compensation and the subsection and synchronization modulation.And then this paper has introduced this system in the hardware and software separately. In the hardware of the fourth chapter, it has briefly introduced the compositions of the hardware and the detailed functions of the each part, including the part of power supply, the part of driving, the part of main controlling and the part of voltage sampling. This paper has introduced the designing flowing of the whole software particularly and the realized processing of the SVM arithmetic, and the frequency conversion controlling processing, the voltage adapting technique, the over-current protection and the errors disposing and so on based the theory relate to the second chapter around the application in the fifth chapter.In the end, this paper has given the conclusion of the experiment and the application future of the system in the sixth chapter.
