Abstract

A half-bridge light emitting diode drive resonance power supply which consist of power factor correction rectifier and inductor-inductor-capacitor resonant topology circuit, the controller for each part is ST6562 and L6599 chip, respectively. This design and analysis has been presented. The MATHCAD is used for system design and to optimize resonant parameters to achieve improved power efficiency of light emitting diode drive resonance circuit. By using sinusoidal analysis we study the characteristics of voltage gain. We achieve zero-voltage-switching and zero-current-switching functions by SABER simulation. The experimental results show that the proposed method achieves high power efficiency 91.5% and smooth electromagnetic interference byÿcomparingÿitÿwith theÿother literatures.
