Abstract :
The authors deal with the solution of a thyristor chopper for the speed control of a DC series motor for mine locomotive drives. They describe the basic functions and a way of driving of the chopper. The differences between chopper control and relay contactor control are underlined. The chopper´s basis functions and its driving equipment are illustrated with the results of tests carried out on the constructed device.
