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 describes the ratio between
active and apparent power is almost one. Line voltage fluctuations can be compensated
very efficiently.
