| 摘 要： | 传统三电平电路的空间矢量调制(Space Vector Pulse Width modulation,简称SVPWM)因运算复杂,限制了它在实际中的应用。提出一种新的SVPWM算法,把空间平面划分为12个直角三角形区域,用空间电压矢量所在的直角三角形所对应的基本开关矢量来合成。对该算法进行了详细的数学推导,并给出了软件流程图。在实验室建立了三电平功率因数校正电路,通过DSP运用该算法来控制,实验结果证明该算法简单易行,便于数字化实现。

| Abstract: | Conventional space vector pulse width modulation(SVPWM)algorithm for three-level circuit is not widely used in practice for its complicated calcu-lations.A novel SVPWM algorithm is proposed.In this novel algorithm,the space plane is divided into 12 right-angled triangle fields,and the space voltage vector is synthesized by several switch vectors corresponding to the right-angled triangle which contains the terminal of the reference vector.Mathematical calculations of this algorithm are performed and the sof... |
