PROJECT DESCRIPTION

The project is designed to develop a device to increase the life of incandescent lamps. Incandescent lamps exhibit very low resistance in cold condition due to which it draws high current while switched ON, resulting in fast failure.

Random switching of lamps may switch the load at peak supply voltage. When such switching occurs while the lamp is having low resistance (cold condition) then the current further shoots up (at the time of peak supply voltage switch ON) leading to premature failure of the lamp.

The proposed project provides a solution by engaging a TRIAC in such a way that the switch ON time is precisely controlled by exactly firing it after detecting the zero cross point of the waveform of supply voltage. This would result in current waveform rising from zero at the time of switch to full value, thereby increasing the life of the lamp.

The project is having comparator which is used for ZVS output. The ZVS (zero voltage switching) is given as reference interrupt to the microcontroller of 8051 family. A push button is used for switching ON the lamp at zero voltage of the supply voltage so the lamp draws current gradually from zero to full value.

Further the project can be enhanced by using three TRIACS, one in each phase for three phase load switching.

Q & A
Q:  Which microcontroller is used in this project?
A:  A 40 pin microcontroller from 8051 family is used in this project.
Q:  How is the lamp life extended?
A:  The lamp is switched on at zero crossing point of supply voltage, drawing least power, thus extending its life.
Q:  How is the zero crossing point detected?
A:  Zero crossing point is detected using Operational amplifiers as comparators.
Q:  Which thyristor is used?
A:  TRIAC BT136 is used as the thyristor.

I was searching in google then i got the Edgefx website. I used Project for Electrical Engineering.
I have decided to buy project from Edgefx because there is an option of DIY( Do it Yourself) kit. I like it a lot. I like complete DIY kit.
The kit was delivered on time with right components.
The customer support has help me in purchasing the project.
I will give reference to my relatives and friends.
