| Abstract: | 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. |
