Power Converter Reliability - DFR and Accelerated Qualification

Power converter failures have been one of the top failure contributors in many electronic products across industry. This presentation addresses the reliability issues and challenges that face today's high performance power converter design and provides a comprehensive reliability analysis and a case study of Design-For-Reliability (DFR) practice on power converters. First, a reliability sensitivity analysis tool is presented and the major reliability contributing factors are analyzed for a typical DC-DC converter design. Then, a case study of power converter DFR practice is provided. The design parameters studied include thermal design, derating design, topology design, mechanical layout, and component quality and applications. Some practical DFR guidelines are provided for power converter reliability design. To meet the short time-to-market demands with high reliability, highly accelerated qualification and supplier management strategy are also discussed.
