TDA4814A

Power Factor Controller IC for High Power Factor and Active Harmonic Filter

Infineon Technologies 

TDA 4814

Typical Application Circuit

Boost Converter with TDA 4814 A

The TDA 4814A control a boost converter as an active harmonic filter, drawing a sinusoidal line

current and providing a regulated DC voltage at the converter output.

The active harmonic filter improves the power factor in electronic ballasts for fluorescent lamps and

in switched-mode power supplies, reducing the harmonic content of the incoming, non rectified

mains current and if suitably dimensioned permitting operation at input voltages between 90 V and

270 V.
