A 24-pulse and 18-pulse composite AC-to-DC converter is a converter using two or more conversion methods in parallel. The converter may include a main rectifier receiving at least a portion of an input AC signal, an autotransformer having an output voltage with lower amplitude than the input AC signal, and a plurality of auxiliary bridge rectifiers, each receiving the output from each leg of the autotransformer. In one embodiment of the invention, the main rectifier may receive a substantial portion of the load current, allowing each of the auxiliary bridge rectifiers to be generally smaller than the main rectifier.
