Abstract
A filter for filtering a three-phase electrical power waveform produces a three-phase output power waveform. The filter has an inductor with three sets of first and second coils, each having a capacitor connected in series therewith. Each of the three sets of first and second coils has a tap intermediate the first and second coils where the output waveform is present, each tap capable of being connected to a load. In some embodiments, the inductor is passive adaptive and includes resistors for reducing current in-rush.
