The increased popularity of LEDs has challenged LED lighting technology to come up with efficient and cost effective solutions on the design of driver circuits. LED driver circuit uses buck, boost and buck-boost converters as switching power a conversion circuit which acts as a constant current source for LED lamps. These converters process a large amount of power during current regulation and hence they are inefficient. In this paper, we propose a highly efficient driver circuit with a fly-back converter as current regulator. The fly-back converter is placed between the dc source and the LED lamp. It uses only a partial power for current regulation and hence the efficiency is improved. Simulation results of open loop highly efficient LED driver with fly-back converter as current regulator is presented in this paper. © 2013 IEEE.
