초록

A system and method for an autotransformer configuration including a plurality of windings which can be used to provide a substantial reduction in harmonics. The autotransformer includes a series of wye windings configured to provide a constant length voltage vector for any given input voltage, and a series of delta windings having a variable length voltage vector based upon turns ratio. The delta winding circuit is electrically coupled with the wye winding circuit to allow circulation of triplen harmonics, thereby reducing the effect on input current wa...
