Abstract
A transformer comprising a core and a plurality of conductor lines. Each conductor line in the plurality of conductor lines comprises at least three windings wound around the core such that a phase voltage at an output connection point associated with a corresponding conductor line of the plurality of conductor lines is substantially a selected percentage of a line voltage for the corresponding conductor line and such that harmonic currents are reduced to within selected tolerances.
