초록

The reliability prediction analysis is a feedback tool that designer uses to provide insight into the component designs. This insight may indicate sensitive components within the design. This paper examines predicted failure rates for hybrid dc-dc converter for spacecraft using MIL-HDBK-217F prediction methodology. The results from part count/stress analysis represent priority components that affect the converter failures. The high priority components are analyzed to find out stress factor based on MIL-HDBK-217F. This information provides an opportunity for designer to improve the reliability of the product in development process.
