Code 284 AC DIMMER OF TWO LOADS USING SINGLE CONTROLLER

This project is intended to attain AC dimmer of two loads using single controller. It is a renowned and aged technique of managing AC power, principally across linear loads for instance heaters brought into play in electric oven.

In this project, we are using a comparator for zero crossing detection which is fed as an interrupt to the arduino UNO3. Here, the arduino 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 arduino. In place of a linear load to be used in the output, a series motor or lamp can be used to verify the output. 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 arduino 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.

Note

Ac dimmer of two loads using single controller Is the project of last year’s engineering project, BE final year engineering project. This project is used for BE last year electrical core electrical and power electronics department students.

Ac dimmer of two loads using single controller of a good Price for the electrical engineering project .it is a very comparative engineering project. It is a very good BE final year and diploma project.it is project for arduino based project idea for the electrical projects is a core electrical project. This project is Bluetooth base project

The engineering projects give in the ELECTROSAL HI- TECH PVT.LTD. The best place for the degree and diploma final year engineering projects as well as for electrical students ‘and core electrical students final year for power electronics student for the golden opportunity.

Ac dimmer of two loads using single controller is an easy project and idea for the electrical core electrical, power electronics degree and diploma base students & 100% output is done
