Abstract
Light Emitting Diode (LED) lighting plays a major role nowadays in industry and commercial applications. An efficient control technique is introduced for low power LED lighting with dimming characteristics. The driver circuit consists of a simple buck-boost converter with dc input voltage. The dimming characteristics are achieved by relating a low and high frequency control signal in order to eliminate flickering and colour shift. Software implementation is performed in MATLAB-simulink for a power rating of 10 W and tested under diverse brightness conditions. The simulation results demonstrate that dimming can be achieved with high efficiency.
