ABSTRACT:
A power supply system is disclosed in which each of the phases of a three phase AC source are rectified and inverted. During inversion high frequency signals are obtained corresponding to the phases of the AC source which are synchronized so that their zero cross points occur at the same time. The high frequency signals are superposed in series to produce an output signal for a load which has a constant power and diminished current distortion.
