| 摘 要： | 提出了一种易于DSP实现的三电平PWM整流器空间矢量脉宽调制(Space Vector Pulse Width Modulation,SVPWM)优化算法.该算法无需开平方和反正切等复杂运算,只需简单的坐标变换,将参考矢量转换到60°坐标系,然后再经过简单的算术运算即可计算出各基本矢量作用时间.仿真实验验证了SVPWM算法的正确性.

| Abstract: | An optimized space vector pulse width modulation (SVPWM) algorithm for three-level PWM rectifier is presented, which is well suited for DSP implementation. The reference vector is first transformed into the sixty-degree coordinate system. Then the duration time of the basic vector can be calculated just through some simple arithmetic operations, avoiding the square root and arctangent operation. The simulation results verified the validity of the proposed algorithm. |
