Title: Analysis and design of a cost effective one stage topology for LED lighting applications
Abstract: Light emitting diodes (LEDs) have great potential to replace existing light sources, like incandescent and fluorescent lamps due to their long life time and higher efficacy. Therefore, also the life time and efficiency of the LED-ballast are important in order to improve the overall system. In addition, size and costs are relevant factors in the highly competitive LED market. The paper presents a very promising one stage topology for LED lighting applications. The highly efficient ballast convinces with its simplicity in structure and control and provides on the one hand a ripple-free LED current, while fulfilling the regulation for the line current harmonics on the other hand. The investigation and optimization is validated by a practical setup.
