Abstract
A single power-conversion LED backlight driving system with high power
factor control is proposed. The proposed converter is composed of a full-bridge
diode rectifier and a quasi-resonant flyback converter. The proposed converter
provides a simple structure, a low cost, and high power factor of 0.988 by
using the novel control algorithm without the PFC circuit. To achieve good
controllability, the novel control algorithm is transformed by adding a nominal
value predetermined to relax its control burden. Detailed analysis and experimental
results for a 90-W prototype are discussed.
