Design Considerations of DC-Link Aircraft Generation Systems

This paper presents a brief history of aircraft generating systems with a comparison of the DC-Link system with the cycloconverter and conventional hydromechanical systems. The elements of the DC-Link systems are described and a discussion of the design considerations of the elements is presented. A brief technical description of each element is presented with block diagrams and simplified schematics. The paper concludes with a description and performance data for a 20 KVA and 40 KVA VSCF system. Hardware pictures of the design implementation are included.
