Abstract

Asymmetric AC to DC autotransformer for turboelectric propulsion, and associated systems and methods are described herein. In one embodiment, an asymmetric AC to DC autotransformer includes: a first coil, a second coil and a third coil of a delta winding Each coil is energized at its corresponding input phase. A first plurality of correction windings coupled to the first coil, a second plurality of correction windings coupled to the second coil, and a third plurality of correction windings coupled to the third coil. A bridge rectifier having a plurality of rectifiers is coupled to respective individual correction windings. Phases of the individual correction windings are asymmetric such that individual phase voltages are controlled relative to the opposite input phase. Voltages are unbalanced relative to neutral.
