DC-DC converter for power LED lighting

The work presents a novel of power electronic driver for Power LED light. This work with dc converter application to an illumination system that connects a battery as a electrical energy to the driver (DC to Dc converter) and load (Power LED). This topology only used single stage converter as a driver between battery supply and power LED light. Therefore, the developed system will reduces power losses, power consumption and cost. These propose topology is very simple and required a single stage of active power switch. This topology used active converter as a main idea without using the transformer. For the future LED driver developments it has to be to be considered that LEDs can also efficiently be supply by pulsating current. This simplifies the converter, control design and reduce the number of component. A prototype circuit that is designed requirement for input only 3.5V - 6V dc and the output is 20V - 33V dc connected to 12 power LED in 15W. Moreover, when circuit in no load the output voltage maximum is 60V. Experimental result show the functionality of the overall system and prove it to be and effective solution for numerous dc to dc converter application.
