| Summary: | LED technology has been used widely in various
applications due to its advantage in term of functionality, high
efficiency, low cost, small size and high reliability. In order to
improve LED performance and prolong LED’s life, High Power
LED driver is been developed. LED driver is used to control
output voltage by using current mode controlled method. This
development of LED driver can increase the LED operation
efficiency, provide high voltage protection, decreases the driver
size and lastly make possible of user friendly installation. Voltage
source is step up by using boost converter as main circuit. In
control circuit, current mode controlled is used to regulate output
characteristic of High Power LED. LTC 3783 is used as PWM
controller to drive the gate and provide pulse signal to the
MOSFET. This driver is designed to operate load that consists of
6 units LED each rating of 5 Watt connected in series.
Theoretical calculation is made to obtain component
specification. The LTspice software is used to simulate the driver circuit by using calculated parameters before move on to hardware implementation. Eagle software is used to design the Printed Circuit Board (PCB). Then, all components are mounted on the PCB which is made of FR4 material. The hardware built is tested experimentally and the output waveform is recorded. |
