通过分析各种SPWM采样算法的优点与缺陷，提出了一种新的SPWM采样算法，并采用Matlab软件计算出在该算法下开关器件的开通与关断时刻点，同时将其与规则采样法、切线采样法的时刻点比较。结果表明：新型的采样算法产生的SPWM脉冲比规则采样法、切线采样法更接近自然采样算法产生的脉冲，计算量远远小于自然算法，体现了该新型采样算法的优越性。最后通过DSP验证该新型算法的可行性。

A novel SPWM sampling algorithm is proposed on the basis of the analysis on advantages and disadvantages of various SPWM sampling algotithms. The on-off time of switch element obtained by the algorithm was calculated with Matlab soft-ware,which was compared with those of regular sampling algorithm and tangent sampling algotithm. The results show this new sampling algorithm is more accurate than regular sampling algorithm and tangent sampling algorithm,and its calculation quanti-ty is much less than the natural sample algorithm,which reflects the superiority of the new sampling algorithm. The feasibility of the novel algorithm was validated by DSP.
