本文探讨了基于物理失效模型的FIDES可靠性预测方法。通过分析不同纬度安装地点的任务剖面,评估了光伏DC/DC变换器的可靠性,为光伏系统在复杂环境下的寿命预测提供了理论依据。

English Abstract

Current methods for reliability prediction are based on physics-of-failure approaches. Such is the case of the FIDES methodology that takes into account the times sequences of operation of an electronic assembly. In this paper, the reliability of a dc/dc converter aimed at photovoltaic applications is explored, considering the mission profiles for three different installations sites, at latitudes ...

该研究对阳光电源的核心产品线(组串式/集中式逆变器及储能PCS)具有极高的参考价值。FIDES方法论强调了任务剖面(环境温度、负载波动等)对电子组件寿命的影响,这与阳光电源在极端气候下(如高温、高海拔)的产品可靠性设计高度契合。建议研发团队将此方法集成至iSolarCloud智能运维平台,通过实时监测的任务剖面数据,实现对逆变器关键功率器件(如IGBT、电容)的剩余寿命预测(RUL)和预防性维护,从而提升全生命周期内的系统可用率,降低运维成本。
