Abstract

The versatile control characteristics of DC motor have contributed in the extensive use of DC motor in the industry. With the increasing use of power semiconductor units, the speed control of DC motor is increasingly getting sophisticated and precise. Speed of the DC motor is controlled by controlling the armature voltage. Armature voltage is controlled using different single phase AC/DC converter. Half converter, semi converter, full converter and dual converter are some of the thyristor based circuits which are used for speed control of DC motor. This paper studies different speed control techniques of DC motor and makes a comparative study of different converter based speed controller techniques.
