Single phase controlled 3-phase 4 wire power converter

A three-phase power converter, the three-phase power converter comprising:

• a converter circuit coupleable to an alternator, the converter circuit to couple to the alternator:
• a first voltage at a first amplitude and a first phase;
• a second voltage at a second amplitude and a second phase;
• and
• a third voltage at a third amplitude and a third phase;
• the converter circuit comprising a combiner circuit, the combiner circuit comprising:
• a plurality of alternator gate drivers;
• and
• a plurality of grid gate drivers;
• a high voltage DC link coupled to the plurality of alternator gate drivers and the plurality of grid gate drivers;
• and
• a control circuit to:
• receive a first input voltage at a first amplitude and a first phase, wherein the first input voltage is an alternating current (AC) voltage;
• control the plurality of alternator gate drivers and the plurality of grid gate drivers of the combiner circuit to form the first, second, and third voltages at the first, second, and third amplitudes and phases based on the first input voltage at the first amplitude and the first phase;
• and
• output the first, second, and third voltages at the first, second, and third phases to the alternator.

A three-phase power converter, the three-phase power converter comprising:

• a first pair of converters coupled to an alternator;
• a second pair of converters coupled to the alternator;
• and
• a third pair of converters coupled to the alternator;
• wherein each pair of converters is to control a phase of three phase power based on an input voltage at a phase and an amplitude received at each converter of the pairs of converters.
