The ICE1PD265G 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. CoolMOS and controller are placed together in one package. This active harmonic filter limits the harmonic currents resulting from the capacitor pulsed charge currents during rectification. The power factor which descibes the ratio between active and apparent power is almost one. Line voltage fluctuations can be compensated very efficiently
