TWO QUADRANT CHOPPER DRIVE FOR THE DC MOTOR SPEED CONTROL

Platform : EMBEDDED

IEEE Projects Years : 2012-13

TWO QUADRANT CHOPPER DRIVE FOR THE DC MOTOR SPEED CONTROL

  

 

AIM:

       The main aim of the project is to develop a speed control system for DC motor using two-quadrant chopper. Using two-quadrant chopper it is possible to demonstrate forward &reverse motoring and braking.

PURPOSE:

       The purpose of the project is to implement a simple and cost effective process to control the speed of DC motors using the most popular technique two-quadrant chopper method.

DESCRIPTION:

          In this project armature is excited by a variable dc supply obtained from two-quadrant chopper. The system is provided with various control keys, such as START, STOP, REVERSE,   FORWARD and REVERSE BRAKE. Using these keys, the user can set the motor to run in any one of the following modes, namely Forward motoring and reverse braking. The speed can be varied by varying the voltage given to the PWM converter (using keypad). The speed of DC motor is directly proportional to armature voltage and inversely proportional to flux. By maintaining the flux constant, the speed can be varied by varying the armature voltage. The direction of rotation is reversed by reversing either field or armature voltage.

       Moreover, the system is provided with Soft start facility i.e., starting the motor without allowing the armature current to exceed the full load current. The Hardware of this system includes uncontrolled rectifier using diodes, chopper using IGBT’S, control keys, speed adjust potentiometer and other logical circuits.

TECHNOLOGY:

      There are several applications with dc motors in our daily life. We require different speeds at different instants depending on the applications. There are several techniques to control the speed of dc motor; PWM technique is one in those. PWM stands for pulse width modulation. Pulse width modulation (PWM) is a powerful technique for controlling analog circuits with a processor’s digital outputs.
