摘要
分析了在电机的驱动和控制系统中,分别采用PWM和PAM控制技术所带来的问题,进而提出将两种技术有效结合起来的PAM/PWM复合变频技术。并针对这种最新的逆变器创新技术在高速AC感应电机控制系统中的应用,给出了相应的设计方案。该技术不但克服了二者单独使用时的缺点,而且保证了高效节能,增加了稳定性。
The problem produced by using PWM and PAM technology separately is analyzed in induction motor driving and controlling system. And then PAM/PWM inverter technology is proposed which combined PAM and PWM efficiently. Simultaneously, the design scheme is provided for its application to AC induction motor driving and controlling system. This inverter technology not only overcome the mentioned problem, also ensure the high power and efficiency.
