Abstract :
This paper presents a new proposal of LED lamp driver using the ZETA DC/DC converter. The main focus is to improve the LED drive characteristcs using the DC/DC converter ZETA, therefore, greater durability and efficiency can be achieved. Through the result experimental it is possible to verify the performance of the converter as well as the luminous efficiency of the LED Lamp.
