USING OF VARIABLE-OUTPUT-VOLTAGE
HIGH PFC AC-DC CONVERTER FOR
COMPACT FLUORESCENT INTEGRAL
LAMPS FEEDING
Abstract – This article presents a design of a variable–
output-voltage high-power-factor-correction AC-DC
converter used for compact integral fluorescent lamps
feeding. Those lamps condition direct incandescent lamp
retrofitting with all the profits that the fluorescent
lighting offers. The main problems with the compact
integral fluorescent lamps sold in Brazil are the absence
of power factor correction (for input power below 60 W)
and the absence of filament pre-heating and input filter.
The proposed rectifier resolves these problems and offers
the dimming function.
