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, i ....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

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.
FEEDBACK-CONTROL THEORY

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 par ....etc
