Abstract


Abstract-LEDs are current driven devices. Variation of temperature can be the cause of instabilities and bifurcations in the LED driver. So it is essential to maintain the stability of LED voltage and current. Driving LEDs from an offline power source faces a number of design challenges like it has to maintain low harmonics in input current,  to achieve high power factor, high efficiency and to maintain constant LED current and also to ensure long lifetime. This paper proposes the technique of harmonics reduction by using parametric optimization of SEPIC based LED Driver. Without optimization of SEPIC parameters input energy will not be properly transferred to the load and this un-transferred energy will be transmitted to the source, as a result the quality of input current will be hampered i.e. harmonics will be contaminated in the input current. Focussing this, the paper has presented the design of a non-isolated integrated-stage single-switch constant current LED driver operating in Discontinuous Conduction Mode (DCM) in Single Ended Primary Inductor Converter (SEPIC) incorporating the design of control circuit with soft start mechanism. This LED driver has achieved a good efficiency and high power factor with reduced harmonics. System stability has been determined and simulation studies are performed to confirm the validity of the LED driver circuit. A laboratory prototype is built to verify the functionality and performance of the proposed LED driver.
