Abstract
Recently, LED (Light Emitting Diode) becomes to be useful to apply for the lightening sources in various electric systems since the power is less consumed with high efficiency, and the size and the weight of LED are small and light, respectively. The LED is derived with constant current and SMPS (switching mode power supply). It is necessary for the industries to improve the power factor (PF) and to design the operational circuit for the development of LED to reduce the power loss in the application of LED lightening. In this paper, a methodology to improve the PF of high power LED module is presented.
