Abstract:

Nowadays, the use of high brightness light emitting diode (HB - LED) is increasing in a lot of outdoor lighting applications such as street lights, floodlights, beacon lights, tunnel lights and security lights, because of its high luminous- efficacy, ease to drive, absence of a mercury problem and long lifetime. LED’S plays a major role in medical field. For example LED’S are used in dermatology, endoscopy, radiology, photo therapy. Mercury lamps make harmful to human beings. This work presents a high power factor (PF), slide mode controlled low total harmonic distortion (THD) light-emitting diode (LED) driver with dimming capability. In addition, the proposed technique ensures a high PF and low THD at any dimming level. The
driver is implemented by using an interleaved capacitor, which is placed between the rectifier and the integrated buck fly back converter
(IBFC) additionally slide mode controller provides attractive features such as fast dynamic response, insensitivity to variations in outputs and external disturbance. MATLAB tool has been used to evaluate our proposed system
