一种不对称规则SPWM采样法
Sampling Method of SPWM with Nonsymmetrical Rules
【摘要】 提出一种两点式不对称规则SPWM工程采样法,使脉冲发生时刻和宽度更接近于自然采样法,从而可有效地降低输出谐波含量。
【Abstract】 A two-dot sampling method of SPWM with nonsymmetrical rules was presented.It made the generation time and width of pulse closer to the nature sampling method,so the content of output humorous wave was reduced effectively.
