Design and analysis of performance and power quality of a led driver

Abstract

This paper presents the design of a driver for 6 W residential LED luminaries with a Flyback topology in discontinuous conduction mode (DCM) using the FT833B12 integrated circuit, which has a constant current control without a feedback circuit. The built prototype is compared to a pair of similar commercial drivers where the characteristics of energy efficiency and current distortion are improved until achieving an efficiency of approximately 82% and harmonic distortion of 93.18%. Using a computational tool and considering the main losses of the built prototype, a study of the performance of the prototype is made.
