PROBLEM TO BE SOLVED: To provide a multi-phase autotransformer having a configuration that improves harmonic mitigation functionality.SOLUTION: A transformer 300 comprises a core 302 and a plurality of conductor lines 304. Each conductor line 305, 307, 309 of the plurality of conductor lines 304 comprises at least three windings 318, 330, 342 wound around the core 302 so that a phase voltage at an output connection point 340, 352, 328 associated with a corresponding conductor line of the plurality of conductor lines 304 is substantially a predetermined percentage of a line voltage for the corresponding conductor line and so that harmonic currents are reduced to within predetermined tolerances.SELECTED DRAWING: Figure 3 |
