Abstract
In one aspect a single-phase transformer is provided that includes: a primary side configured to receive a primary line to line voltage of a three-phase source; and a secondary side configured to output a secondary line to line voltage having a zero amplitude and substantially similar first and second line to neutral secondary voltages. In other aspects of the invention, systems and methods are provided for mitigating harmonics that employ the transformer.
