Abstract
The invention comprises a method and apparatus for processing power, comprising the steps of: generating/using 3-phase power; feeding an AC drive with the 3-phase power, the AC drive generating a first output; and transforming the first output with a zigzag transformer, the zigzag transformer linked to at least one load output/load connector. The method and apparatus comprises an optional filter for filtering the 3-phase power prior to the step of transforming, the filter including a distributed gap core material.
