Description
This project is intended to attain vital cycle switching – a technique to get rid of complete cycle, cycles or fractions of cycles of an AC signal. It is a renowned and aged technique of managing AC power, principally across linear loads for instance heaters brought into play in electric oven. However, the concept of achieving the cycle stealing of voltage waveform by the use of microcontroller can be very precise as per the program written in assembly C language so that the actual time-average voltage or current experienced at the load is proportionately lower than the whole signal if applied to the load.
In this project, we are using a comparator for zero crossing detection which is fed as an interrupt to the microcontroller of 8051 family. Here, the microcontroller delivers the output based on the interrupt received as the reference for generating triggering pulses. Using these pulses, we drive the Opto-isolators for triggering the TRIAC to achieve integral cycle control as per the input switches interfaced to the microcontroller. In place of a linear load to be used in the output, a series motor or lamp can be used to verify the output. One side effect of utilizing this scheme is an imbalance in the input current or voltage waveform as the cycles are switched on and off across the load. A lamp is provided in this project in place of a motor for demonstration purpose. The project output with a lamp appears to be a simple project of lamp flickering but the real objective is to verify in a CRO/DSO ,whether at the random switching also the load switches on at zero cross of the waveform or not.
The power supply consists of a step-down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to a DC using a Bridge rectifier. The ripples are removed using a capacitive filter, and it is then regulated to +5V using a voltage regulator 7805, which is required for the operation of the microcontroller and other components.
Furthermore, this project can be enriched by using a feedback mechanism to automatically maintain the desired output to the load by appropriate cycle stealing.

Retesha Hawaldar –
I needed a electrical project for final year so I went for this project, the project was well tested also it is in plug and play condition. And it’s impressive as it gives almost accurate results.
Johan Sumith –
Very much dedicated , highly skilled team of engineers . Can get the required project at an affordable price in the promised time.
The most important part is after sale service which is very much admirable

Lakhan Khade –
Well i got the AUTOMATIC POWER FACTOR CORRECTION USING ARDUINO project and i was surprised to see it delivered in such a good condition. I was afraid that sending a delicate circuit in through international shipping may damage it, but their packaging is extremely good.
Amit Inamdar –

Godstime (Nigeria) –
A Typical day at work very competitve learned to never to take the objection of one call in to the next management was very encour again when was an off day the morel of the very work was the hards part of the job was tring the leards of the team form month to much the most enjoble part of my job three was the great bounes i received for over achivment
Deepa Patil –
Good project and best service
R. Rahul –
Nice customer support .thank for online video call support. thank you Electrosal.
Rohit Powar –
My kit delivery was a day late but no problems since my submissions were late, well I surely learned a lot from this kit it has very detailed explanation documents and videos. Overall a nice experience.
Puneeth Rajkumar –
The project quality was very good, I like the way they provide all system development videos along with the kit. I had ordered the AUTOMATIC POWER FACTOR CORRECTION USING ARDUINO kit & am happy to have ordered from here.. no issues at all
Pushpa Chavane –
The online explanation system for my software project kit was wonderful. I saw it 3 times and once again before my final presentation, gave me detailed knowledge of the opinion mining project I bought.
