    INVESTIGATION OF SEPIC CONVERTER POWER FACTOR CORRECTION TOPOLOGIES FOR LED LIGHTING APPLICATIONS
    Sreemallika R*, R Seyezhai

    LED is an emerging technology that has the potential to displace inefficient incandescent lamps and mercury-filled fluorescent lamps. The design of the power supplies that drive the LED systems is very crucial as high power quality has to be maintained. The single ended primary inductance converter (SEPIC) converter is used widely for LED applications as a singlestage power conversion is possible i.e. it is possible to achieve its output voltage lower or higher than the input voltage and also a high power quality can be achieved. In this paper, various SEPIC power factor correction converter topologies for LED applications were explored. A novel SEPIC PFC converter was also proposed which exhibits a better power factor than the conventional converters. The proposed converter works under continuous conduction mode (CCM) to drive the LED Lamp. Power quality indices were evaluated to verify the performance of the system. Results were verified by simulation studies using MATLAB/simulink.
