摘要
本文对基于空间电压矢量的变频调速系统进行了研究，叙述了空间电压矢量的原理，对TI公司第三方软件的对称空间电压矢量的算法进行了分析，并用Simulink对该方法进行了仿真，对两个零矢量的作用时间和作用顺序进行了分析，指出空间电压矢量PWM实质上是一种谐波注入的调制方法。
基于TI公司的TMS320F240控制芯片，介绍了对称空间电压矢量硬件设计和软件设计，采用TMS320F240设计了一款用于电机变频调速的数字控制器，该控制器上设计有键盘和LED显示，可以设定和动态显示电机运行频率。在取得基于TMS320F240数字控制器的基础上，设计了一款基于TMS320LF240A的数字控制器。
利用IPM智能功率模块，设计了采用基于TMS320F240数字控制器的对称空间电压矢量的开环变频调速系统的原理样机，对电机进行了空载实验，给出了它们的实验结果，实验结果和理论分析相一致。
Variable frequency speed regulation system based on the voltage space-vector is researched in this paper, the principle of the voltage space-vector is presented, and the third part' s software strategy of voltage space-vector is analyzed, the method of the third part' s software of voltage space-vector is imitated with Simulink. At the same time, the duty time and duty order of the two zero-vector are analyzed and showed that the voltage space-vector PWM is actually a modulated method by adding the harmonic to the sine wave.
Based on the TMS320F240 controller produced by TI Company, the hardware and software designation of the symmetrical voltage space-vector PWM is presented. Designed a digital controller with TMS320F240 to modulate the speed of the Motor, in which the keyboard and LED display are bedded. It can be to set the frequency of Motor and display the run frequency of Motor in real time. After the digital controller of TMS320F240 has been finished, designed another digital controller with TMS320LF2407A.
Prototype of the symmetrical typical voltage space-vector of open-loop variable frequency speed system is designed by using the TMS320F240 digital controller and the IPM(intelligent power model),With which had a exam on the Motor and the experimental results are also given. From the results we can conclude that the results are according with the theory analysis.
