#G-5, Ratna Complex, Ameerpet,
#310, OPP. Kalaniketan, Dilshukh Nagar


AIM:
The main aim of the project is to develop a speed control system for DC motor using four-quadrant chopper. Using four-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 four-quadrant ....etc

DC MOTOR CONTROL USING CHOPPER


ABSTRACT

The speed of separately excited DC motor can be controlled from below and up to rated speed using chopper as a converter. The chopper firing circuit receives signal from controller and then chopper gives variable voltage to the armature of the motor for achieving desired speed. There are two control loops, one for controlling current and another for speed. The controller used is Proportional-Integral type which removes the delay and provides fast control. Modeling of ....etc

construction and working of four quadrant chopper pdf

Abstract

In chopper circuits, unidirectional power semiconductors are used. If these semiconductor devices are arranged appropriately, a chopper can work in any of the four quadrants. we can classify chopper circuits according to their working in any of these four quadrants as type A, type B, type C, type D and type E. Let us now take a look of these classifications and the characteristics of various classifications.

Type A Chopper or First Quadrant Chopper

This type of chopper is s ....etc

The basic principle of the DC motor is a device which converts DC energy into mechanical energy. When the current carrying armature is connected to the supply end though commentator segment, brushes are placed within the North South Poles of permanent or electromagnets. By using these electromagnets operating principle is depends on the Fleming s left hand rule to determine the direction of the force acting on the armature conductors of the DC motor.

A variable-frequency drive (VFD) (also termed adjustable-frequency drive, variable speed drive, AC drive, micro drive or inverter drive) is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage.

VFDs are used in applications ranging from small appliances to the largest of mine mill drives and compressors. However, around 25% of the world's electrical energy is consumed by electric motors in industrial applications, which are especially cond ....etc
