Abstract
A method for designing a transformer using three secondary winding phase shift angles and a minimized core cross-sections. The method includes receiving an indication of an acceptable level of total harmonic distortion (THD) for the transformer, identifying a desired number of secondary windings per output phase of the transformer, simulating performance of various models for the transformer various potential phase shift angles, wherein each of the various models includes a set of phase shift angles for the secondary windings of the transformer. The method further includes identifying, based on the simulation, a transformer model that both has no more than three unique phase shift angles in the set and exhibits a primary side THD that is within the acceptable level, identifying an optimized core cross-sections, and reporting the identified transformer model having the three unique phase shift angle and the optimized core cross-sections.
