为了确定电力电子变换器的工业要求和可靠性期望，进行了问卷调查。这项调查是主观的，调查对象包括许多知名的半导体制造商、集成商，以及航空航天、自动化、电机驱动、公用事业电力和其他行业的用户。根据调查，功率半导体器件是最脆弱的元件。认为环境应力、瞬态应力和重载应力是电力电子系统设计和正常运行时应考虑的主要应力来源。本文还强调，应急人员迫切需要更好的可靠性监测方法和指标。
A questionnaire survey was carried out to determine the industrial requirements and expectations of reliability in power electronic converters. The survey was subjective and conducted with a number of high-profile semiconductor manufacturers, integrators, and users in the aerospace, automation, motor drive, utility power, and other industry sectors. According to the survey, power semiconductor devices ranked the most fragile components. It was concluded that main stresses were from the environment, transients, and heavy loads, which should be considered during power electronic system design and normal operation. This paper has also highlighted that there is a significant need identified by the responders for better reliability-monitoring methods and indicators.
