摘　　要：传统的中小型发电机励磁设备一般采用模拟电子技术实现,电路复杂,智能化程度低,可靠性差。文章提出了用一种基于AT89C2051定时器为基础的新型PWM波形产生方法,运用到传统的中小型发电机励磁设备控制器中,简化了原控制器电路,提高了其智能化水平,并显著提高了发电机励磁设备的可靠性。Traditional Small or Medium generator excitation equipments based on Analog Electronic Technique have complicated electro circuit and low Intelligence and reliability. A new PWM waveform generating method based on AT89C2051 timer is proposed and used in traditional Small or Medium generator excitation equipments, which not only simplify the electro circuit but also improve Intelligence and reliability.
