High-performance AC/DC converter for high-frequency power distribution systems: analysis, design considerations, and experimental results

This paper presents a description and analysis of a new AC/DC converter topology for use in the high-frequency power distribution system in Space Station Freedom. Steady-state analysis of the converter is provided, the performance characteristics presented, and transient behavior studied. The proposed converter has close-to-unity rated power factor (greater than 0.98), low total harmonic distortion in input current (less than 5%), and high conversion efficiency (greater than 96%). Finally, to verify the proof of-concept, a bread-board converter was built.<
