| 摘 要： | 电压空间矢量(SVPWM)调制方式把逆变器和电机看作一个整体处理，具有所得模型简单，便于数字化实现，并具有转矩脉动小、噪声低、电压利用率高等优点。近年来在变频调速系统中逐渐得到了应用和重视。本文叙述了空间电压矢量的基本原理。讨论了不对称SVPWM波形及两种对称SVPWM波形的产生方法及优缺点。利用数字信号处理器TMS320F240产生基于恒压频比控制的对称SVPWM调制波形。实验结果表明SVPWM的调制波。和准优化PWM有异曲同工之处，其实质也是一种带谐波注入的调制方法。

| Abstract: | The inverter and motor is Treated as one part in voltage space-vector. So it has simple model and can be realized using digital technic. Low torque pulse, low noise and high using rate of voltage is the advantage of SVPWM. The fundamental principle of voltage space-vector(SVPWM) is recounted in this paper. The present paper discusses advantages and disadvantages between asymmetrical SVPWM wave and symmetrical SVPWM wave. The method of producing SVPWM is also presented. Symmetrical SVPWM wave under V/F control is produced using digital signal processor TMS320F240 in the paper. The wave produced by SVPWM is similar with optimization PWM. |
