| Abstract: | The DC chopper based on 89S52 is designed in this composition. The center of the control system of the DC chopper is composed of the single chip microprocessor. The main circuit uses IGBT as the chopper switching. Because of the outstanding features of single chip microprocessor 89S52, there are advantageous performance in this DC chopper. The system has advantages of little elements, simple configuration, high reliability, high accuracy. The paper also introduce the way of protection which deals with over current and over voltage. |
