摘要: This study presents a universal-input AC electronic lighting system using non-isolated SEPIC PFC rectifier to drive and control power light emitting diodes (LEDs). One energy regenerative snubber is proposed reduce the converter switching losses aiming improve overall efficiency. A linear current regulator employed provide features of flicker-free dimming capability for system. The operation stages as well theoretical waveforms main equations at steady state are described in details. To efficiency impairment, conditions achieving minimum loss also detailed. loop designed results from small-signal analysis presented track optimal operating point real-time. Experimental prototype 90 265 V output 15 100% 35 LEDs / 42 W verify analyses carried out.
