摘要
本文介绍了一种新型的ＳＰＷＭ脉冲形成方案，它以８０３１单片机作为专用ＳＰＷＭ脉冲形成单元ＳＬＥ４５２０的外围硬件支持，通过软件编程的方法来产生ＳＬＥ４５２０所需的时钟等要求，整个ＳＰＷＭ脉冲形成部分的调频范围为０．１６～２６０４Ｈｚ，文中不但详细介绍了该ＳＰＷＭ脉冲形成方案的组成，而且给出了其在实际系统中的实验结果。
This paper presents a novel SPWM pulse scheme which takes 8031 single-chip microprocessor as the special peripheral hardware of SPWM pulse unit SLE4520. The clock frequency etc. necessary for SLE4520 is produced by software programming. The variable-frequency of the whole SPWM pulse ranges from 0. 16Hz to 2640Hz. In this paper,not only the composition of the SPWM pulse scheme is detailed,but also its experiment results are given.
