INTRODUCTION
This assignment is basically designed to demonstrate the use of controllers in DC motor which consists of two stage ,electronic stage that is controlled by 8 bit microcontroller and second is the mechanical stage consisting of gear box which controls the motion of DC motor to provide a impulse to electronic stage which generates a resultant signal to control the parameters of controller.

speed control of ac motor using igbt ppt free download

Abstract

This paper presents design and analysis of a three phase induction motor drive using IGBT s at the inverter power stage with volts hertz control (V/F) in closed loop using a microcontroller. A 1HP, 3-phase, 415V, 50Hz induction motor is used as load for the inverter. Oscilloscope is used to record and analyze the various waveforms. The experimental results for V/F control of 3-Phase induction motor using GSM clearly shows constant volts per hertz and stable inverter line to line ....etc

Abstract-
In this paper, a new complementary gate driver for power metal-oxide semiconductor field-effect transistors and in sulated gate bipolar transistors is presented based on the use of a piezoelectric transformer (PT). This type of transformer has a high integration capability. Its design is based on a multilayer struc ture working in the second thickness resonance mode. A new de sign method has been used based on an analytical Mason model in order to optimize the efficiency, the available power at the trans former secondary ends, and ....etc

Active Gate Control for Current Balancing of
Parallel-Connected IGBT Modules
in Solid-State Modulators

Abstract

In modern pulsed power systems, often, fast solidstate
switches likeMOSFETs and insulated gate bipolar transistor
(IGBT) modules are used to generate short high power pulses. In
order to increase the pulsed power, solid-state switches have to be
connected in series or in parallel. ....etc

scada for ac motor controller with igbt based control system

Abstract

This paper presents practical laboratories for teaching purpose in Supervisory Control and Data Acquisition (SCADA) systems. A SCADA system is described in terms of architecture, process interfaces, functionality, and application development facilities. These concepts are implemented on an integrated automation system, particularly for digital control of electric drives with distributed peripheral, i.e., Totally Integrated Automation with Democase from Siemens. Using this s ....etc

12-PULSE HVDC TRNSMISSION SYSTEM BY USING IGBT VALUES


ABSTRACT

In this project an attempt has been made to analyze the effect of Using IGBTs rather than semiconductor devices such as Transistors, SCRs in the converter stations for HVDC transmission.
The main parts of any basic HVDC transmission system are converter stations transmission line and DC switch gear and protection equipment. Till now the main devices that are used in converter stations for the purpose of rectification and inversion are SCRs. B ....etc

ppt speed control dc motor using igbt

INTRODUCTION

Developments of high performance motor drives are very essential for industrial applications. A high performance motor drive system must have good dynamic speed command tracking and load regulating response. DC motors provide excellent control of speed for acceleration and deceleration. The power supply of a DC motor connects directly to the field of the motor which allows for precise voltage control, and is necessary for speed and torque control applications. DC drives, because of their simp ....etc

SPEED CONTROL OF DC SHUNT MOTOR USING MICRO CONTROL BASE


INTRODUCTION:-
DC motor speed controllers are very useful for controlling the motion of robotic and industrial automation systems. The controller presented here uses the PWM technique. The PMW wave for speed control is generated using Atmel AT89C51 microcontroller. To control the speed of the DC motor, you need a variable power supply. When the DC motor is switched on, it take the certain time to reach the full speed. As ....etc
