The project is designed to control AC power to a load by using firing angle control of thyristor. Efficiency of such power control is very high compared to any other method.
The project uses zero crossing point of the waveform which is detected by a comparator whose output is then fed to the microcontroller. The microcontroller provides required delayed triggering control to a pair of SCRs through opto isolator interface. Finally the power is applied to the load through the SCRs in series. This project uses a microcontroller from 8051 family which is interfaced through a push button switch for increasing or decreasing the AC power to the load. A lamp is used in place of an induction motor whose varying intensity demonstrates the varying power to the motor. The varying power results in variation in speed of the motor.
The project can be further enhanced by using direct 230 volt supply instead of 12 volt AC to the bridge rectifier for achieving higher voltage control for charging number of batteries in series.

    I got to know about edgefx through my senior he has suggested me the website details. So, i have directly visited the website. I have decided to buy project from edgefx because my senior has suggested me. I like audio-visuals of the project. Customer support team has helped me in purchasing the project & the kit was delivered in time with right components. i want to give reference to my juniors and friends.

    I got to know about edgefx through google then i got to know about edgefx. I was searching my project title in google then i got to know about edgefx. There is no other website like this that is providing very good project like this. I like complete kit. the support team has helped me in purchasing the project & the kit was delivered in time with right components. i will definitely give reference to my juniors.

    I come to know about Edgefx through Internet and Last year even my friends taken the project from Edgfx. I used the keyword- electronics projects to find Edgefx in Google.I decided to buy a kit from Edgefx because price is reasonable and finishing looks like reliable.No my kit delayed for a day.One of your Executive helped me while purchasing the project.Delivery should be in time.

    I come to know about Edgefx through Internet. I used Btech projects for final year as a keyword in Google.I decided because it is reasonable, quick delivery and nearest distance.The kit delayed for two hours.Ms. Suvarna replied to my call and I placed an order through her guidance.Improvements should be in the Project description and overview.
