Abstract:
A multi-pulse transformer for an industrial machine, the multi-pulse transformer including a primary winding and a plurality of secondary windings. The primary winding coupled to a power source, the power source operable to generate a primary voltage. The secondary windings are coupled to one or more converters, each of the secondary windings are phase shifted with respect to the primary winding. The converters are operable to provide a secondary voltage to at least one component of the industrial machine. Wherein the multi-pulse transformer converts the primary voltage to the secondary voltage and attenuates harmonic distortions caused by the converters and the component of the industrial machine. Additionally, the secondary voltage is at a voltage less than the primary voltage.
