摘要： A power system for providing an output power to a load is provided. The system comprises a generator configured to generate an alternating current input power and a power converter system coupled to the generator and configured to generate an output power and provide the output power to the load through at least one transformer. The system further comprises a converter control system coupled to the converter system and configured to drive the converter system in an interleaved pattern to reduce harmonic components in the output power and the alternating current input power.

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.
