The need to conserve energy has led to development of low power consuming devices. Out of many one such device is LED used for lightning purposes. The LED requires a specific amount of voltage and current depending upon the type, rating and amount of luminous intensity. This supply to LED is fed through the LED driver circuit comprising of DC to DC converter. The objective is to perform the comparative study on various types of DC to DC converters for LED driver unit and doing simulations and implementing practically. The target is to determine the converter circuit that suits best for necessary equipment. Here the desired equipment is a LED which are used in commercial as well as house hold lightning purposes. There are many kinds of ratings available out of which target power is 21W and according suitable supply voltage of 230V.With an array of LEDs, the main challenge is to ensure every LED in the array is driven with the same current. Placing all the LEDs in a series string ensures that exactly the same current flows through each device. MATLAB Simulation is used for the initial validation of the proposed scheme and for the selection of circuit parameters. Actual controller is implemented using AVR atmega32 microcontroller.
