Abstract

Summary

The different uses of DC motors (for both domestic and industrial) make changing the speed from one level to
another very important to suit the required speed needed for any particular purpose. The control of this
machine can be done using AC/DC power converters. However, the edge which these power converters have
over themselves when used to control the speed of these machines are not known. This paper hereby compares
using MATLAB/SIMULINK the control of separately excited DC motors, series DC motors and shunt DC
motors by AC/DC power converters. The types of AC/DC power converters considered are the half wave,
single phase converter drive; single phase, semi-converter drive and single phase, full wave, semi-converter
drive. Results show that all motors have their maximum speed with a thyristor firing angle of 0 rad and
decrease as the firing angle is increased. For the separately excited DC motors, average speeds change of -
94 rpm/rad and -160 rpm/rad were realized for the half wave/semi-converter drives and full wave drives
respectively. Furthermore, it can be can be deduced that using the full wave converter drive performs speed
changing operations at a faster rate than their half wave or semi converter drive counterparts for the various
types of DC motors.
