• Manufacturer Part Number: TDA4814A
• Description: Power Factor Controller IC for High Power Factor and Active Harmonic Filter
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

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.
