摘　　要：指出用于CVCF逆变器控制中的SPWM及普通PWM信号产生方案的不足,在此基础上提出一种通过脉宽调制阶梯波来合成正弦波的方案。理论分析和实验表明,该方案具有输出基波电压高、谐波分量小的优点,且电路结构极为简单。文中给出了实现方案。Points out the inadequacy of the sine PWM (pulsewidth modulation)signal and general PWM signal for CVCF (constant voltage & constant frequency)inverters and proposes the PWM Step-wave Signal as a new scheme.Experimental and theoretical result showes that the new signal has a wide range of voltage regulation,a high voltage of first harmonic and a low voltage of other harmonics.The generating circuits for the new signal are given.
