Abstract
A nearly 2 to 1 boosting mufti-phase AC-to-DC converter may include a main rectifier, an auxiliary rectifier; and an autotransformer connected to the main rectifier and the auxiliary rectifier. The autotransformer may include a plurality of interconnected windings arranged in a plurality of legs, with one of the legs for each phase and with each leg including a plurality of windings, wherein all but one of the windings of each leg have equal turns ratios and one of the windings of each leg has a turns ratio that is less than the turns ratio of all of the other windings of the respective leg.
