Power conversion system and method

摘要

A power generation system for supplying a resultant output voltage is provided. The system comprises a power converter system (16). The power converter system comprises at least two power converter bridges (18, 20), each configured for switching at a low frequency and generating a corresponding converter output voltage including a fundamental voltage component and harmonic components, and at least two power converter transformers (22, 24). Each power converter bridge is coupled to a primary winding (30, 32) of a corresponding power converter transformer and a secondary winding (34) of one power converter transformer is coupled to a secondary winding (36) of a second power converter transformer. The resultant output voltage comprises a sum of the fundamental voltage components of each converter output voltage.
