Thyristorised Speed Control of DC Motor Using Semi-Converter

EasyChair Preprint 10196

Abstract

Control characteristics of DC motor have contributed in the extensive use of DC motor in the industry. With the increasing uses of power semi conductor units, the speed control of DC motors is increasingly getting sophisticated and precise. Speed of the DC motor is controlled by controlling the voltage armature.Voltage of armature is controlled using different single phase AC/DC converters. 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.

Motors are widely used in industry because of its low cost, less complex control structure and wide range of speed and torque. There are many methods of speed control of DC drives namely field control, armature voltage control and armature resistance control methods. DC motors provide high starting torque which is required for traction applications. In DC motor control over a large speed range, both below and above the rated speed can be achieved quite easily. DC motors have inherent disadvantages that it needs regular maintenance and it is bulky in size.

Keyphrases: Semi-conductor, Thyristor, motor, speed controller
