Dual mode low-pass sine-wave filter, suppressing the switching frequency
and smooth out the phase-to-phase and phase-to-ground motor voltages to
become sinusoidal.

Key-features:
Up to 1000 meter unscreened motor cable
Reduction of acoustical switching noise from motor
Elimination of motor bearing currents
Elimination of motor insulation stress
Extends motor service lifetime.
