An electromechanical power transfer system that converts direct current (DC) electrical power to variable mechanical power, comprises: a source of DC that has a neutral ground, a positive potential output with a level of electrical potential that is positive relative to the neutral ground and a negative potential output with a level of electrical potential that is negative relative to the neutral ground; a multiphase alternating current (AC) dynamoelectric machine with an even number of phases; and a neutral point clamped (NPC) inverter system that receives electrical power from the positive and negative potential outputs the DC source to generate multiphase AC power for the dynamoelectric machine with the same number of even phases that exhibits no common mode potential/noise.
