摘    要:在对正弦脉宽调制(SPWM)信号进行分析的基础上,提出了一种改进的SPWM信号计算方法,即对脉宽差幅值进行分段线性量化,使求解整个SPWM信号的脉宽只需要很少的几个特征参数。该方法与传统SPWM方法相比,不但大大降低了实现的复杂性,而且达到了预期的谐波抑制效果,经复杂可编程逻辑器件(CPLD)验证,实际的谐波测试结果表明本方法是有效的。

关 键 词:谐波  抑制调制器  正弦脉宽调制  分段线性近似

Abstract:According to the study on SPWM signal, this paper proposed a novel SPWM generate method which utilizes piecewisc linear approximation to quantify the pulse-width's difference hetwcen two adjacent pulses. With this method, it only needs few characteristic parameters to calculate the SPWM signal and greatly reduces the complexity of the realization of SPWM signal. This method was validated by the use of CPLD and the practical test results show that it has a good performance in harmonic-suppression.
Keywords:harmonic waves  suppressed modulators  sinusoidal pulse-width-modulation (SPWM)  piece- wise linear approximation
