摘要
本文介绍一种智能型、高精度PWH控制器SA4828,其控制实行全数字化产生三相脉宽调制波形,本文采用此器件设计大功率直流电源应用于22KW直流电机测试,对感性负载表现出具有纹波小、响应迅速、硬件电路简洁、控制简单易于编写的优点。
We will introduce an intellectualized, high-precision PWM controller-SA4828. It uses full digital manners to produce modulating wave. In this paper, we use this apparatus to design a high-power DC electrical source, which is applied to test DC motor. It has many merits, such as small ripple, quick response, simple hardware circuits, easily controlling and programmed in the inductance load situation.
