摘要
本文提出了一种基于EPROM存贮的新型全数字式PWM调制器。该调制器具有占用机时极少,控制规则可调,控制精度较高,电路简单等优点,特别适用于高频调制。本文对该调制器的基本原理进行了分析,并按该原理制作了一台单相PWM发生器,载波频率为20kHz,所得波形满足要求。
A novel EPROM-based digital PWM modulator is proposed in this paper,which has the followinga dvantages such as occuping a little time of the microprocessor,adjustable control strategy,more accurate control and simpler circuit. It is especially fit for high frequency modulation. The fundamental principle is analysed in this paper. A single phase PWM modulator is implemented based on this principle, with 20kHz carrier frequency. The waveform is satisfied.
