Abstract :
High voltage power supplies (HVPS) have traditionally been among the least reliable components in airborne display electronics. NAVMAT P-4855-1A highlighted the source of these problems in industry's failure to apply appropriate methods for high voltage design, development and materials selection. Also, the nature of airborne HVPS is such that MTBF prediction using MIL-HDBK-217 has shown very little correlation to actual field performance. These problems continue today. In recent years, ELDEC has developed a methodology to systematically evaluate and improve the design and long term reliability of high voltage power supplies. This methodology has been successfully applied under a recent Air Force CRT PRAM contract to improve HVPS reliability in AWACS aircraft situation displays. The accelerated testing portion of the methodology has been recommended to the Air Force for adoption as a standard to be used in the procurement of future high voltage power supplies. Elements of the methodology are described.
