ABSTRACT:
A power generation system for supplying a resultant output voltage is provided. The system comprises a power converter system. The power converter system comprises at least two power converter bridges, 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. Each power converter bridge is coupled to a primary winding of a corresponding power converter transformer and a secondary winding of one power converter transformer is coupled to a secondary winding of a second power converter transformer. The resultant output voltage comprises a sum of the fundamental voltage components of each converter output voltage.
