AC MOTOR SPEED CONTROL USING TRIAC
When we are furnishing a home, light is everything. The light level in a room dictates what we can and cannot do and it has a huge effect on how we feel.
The problem is that people need to use some rooms for multiple purposes, and these different functions call for varying amounts of light. The dimmer switch is a handy electrical component that allows the user to adjust light levels from nearly dark to fully lit by simply turning a knob or sliding a lever.
Early dimmer switches w ....etc

Introduction
The zero-cross family of optically isolated triac drivers is an inexpensive, simple and effective solution for interface applications between low current dc control circuits such as logic gates and microprocessors and ac power loads (120, 240 or 380 volt, single or 3-phase). These devices provide sufficient gate trigger current for high current, high voltage thyristors, while providing a guaranteed 7.5 kV dielectric withstand voltage between the line and the control circultry. An integrated, ze ....etc

Introduction

The Parallel Port is the most commonly used port for interfacing home made projects. This port will allow the input of up to 9 bits or the output of 12 bits at any one given time, thus requiring minimal external circuitry to implement many simpler tasks. The port is composed of 4 control lines, 5 status lines and 8 data lines. It's found commonly on the back of your PC as a D-Type 25 Pin female connector. There may also be a D-Type 25 pin male connector. This will be a serial RS-232 port and th ....etc

DTMF Based Interfacing and Control of Induction Motor using TRIAC



The AC induction motor is the most commonly used AC motor in industrial application because of its simplicity, rugged construction, and relatively low manufacturing costs. The reason that the AC induction motor has these characteristics is because the rotor is a self-contained unit, with no external connections. This types of motor devices its name from the fact that AC currents are induced into the rotor by a rotating magnetic field.
