Evaluation of Shipboard Reliability of AN/BQQ-5 Switched-Mode Power Supplies,

Abstract

The IBM power supply units in the AN/BQQ-5 sonar system have established a record of reliable performance over the course of tem years of system operation. Due to their excellent field performance, these units provide a model for present and future Navy power supply programs. Future power supply designs can make use of this model in several ways: Actual shipboard reliability of critical power supply components can be analyzed to determine primary failure modes, and the lessons learned can be applied to new power supply designs. Component technology improvements developed during this program can be used to augment the reliability of new designs. Manufacturing methods used in this program, such as burn-in and parts screening procedures, can help to improve the reliability of new designs. The actual failure rates of critical power supply components can be referenced to failure rates predicted from MIL-HDBK-217.
