Abstract
A dual-output AC-DC power converter with balanced DC output voltages is described. The DC power source has balanced DC voltage outputs relative to DC midpoint irrespective of DC load imbalance. The input to the power source is three-phase four-wire AC voltage source. Current draws from the AC three-phase voltage source have 12-pulse near sinusoidal waveform. Ripple voltage from DC positive rail to DC negative rail is 12-pulse.
