摘要:The flexible control of DC motor has been donated in the extensive use of DC motor in the era of industry, as the increasing usage of semiconductor power converter units. The speed control of DC motor is very sophisticated and specific. The speed of DC motor has been controlled by controlling the armature voltage by using thyristors. The armature voltage is controlled by using the different types of AC to DC semiconductor converters such as half wave converter, semi converter and full wave converter by using thyristor-diodes. This paper shows the experimental comparative analysis of the DC motor speed control by using the different power converter topologies performed at the Quaid-E-Awam University of Engineering Sciences and Technology, Nawabshah lab.
