Description

The TDA4863 IC controls a boost converter in a way that sinusoidal current is taken from the single phase line supply and stabilized DC voltage is available at the output. This active harmonic filter limits the harmonic currents resulting from the capacitor pulsed charge currents during rectification. The power factor which decibels the ratio between active and apparent power is almost one. Line voltage fluctuations can be compensated very efficiently.
