Abstract
A power converting apparatus and method providing for the addition of a fourth power connection wire to the neutral point of the normal three phase load circuit. This allows delivery of combined current from the center of the DC link voltage to load. The added control enables a third harmonic injection to flow and allows for increased power rating per peak amp handled by the conversion system. Limiting of faults to the positive half versus the negative half of the DC system allows for more robust behavior when encountering these fault conditions.
