摘　　要：SA4828是英国MITEL公司生产的三相SPWM波形产生集成电路,他可提供全数字化控制的三相脉宽调制波形,易于与大多数型号的单片机接口,而且具有编程简单方便,修改灵活的特点。详细介绍了SA4828的工作原理及其参数设置方法,并给出了其在飞机发电机控制器检测用信号源中的硬件连接原理框图,此外还给出了SA4828初始化与控制部分的程序流程图。SA4828 is a kind of integrate circuit produced by MITEL Corporation,it can generate all - digital three - phase SPWM wave and can easily interface with many kinds of single chips. What＇s more,it is simple to program and modify. The paper details introduces work principle of SA4828 and method of parameters setting. Hardware- connecting principle chart of SA4828 that applies to signal source of airplane generator controller is also given. Furthermore,program flow chart of SA4828 initialization and control is brought out, conclusion of the paper is drawn out finally.
