Abstract
A boosting AC-to-DC converter may include a main rectifier, first and second auxiliary rectifiers, and an autotransformer. The autotransformer may include a plurality of winding assemblies each having a primary terminal connected to an AC power source, a main secondary terminal connected to the main rectifier, a first auxiliary secondary terminal connected to the first auxiliary rectifier, and a second auxiliary secondary terminal connected to the second auxiliary rectifier. Impedance between the primary terminal of each of the winding assemblies and the main rectifier is less than impedance between the primary terminal of each of the winding assemblies and either the first auxiliary rectifier or the second auxiliary rectifier. Impedance between the primary terminal of each of the first winding assemblies and the first auxiliary rectifier is different from impedance between the primary terminal of each of the winding assemblies and the second auxiliary rectifier.
