This paper describes the implementation of a comprehensive Virtual Test Bench VTB aimed at the reliability prognosis for photovoltaic inverters. The scheme is based on the Design for Reliability approach, and uses the FIDES reliability prediction methodology to include information about the mission profile. That, in combination with the selected computational tools, provides a fast, low-cost tool for the analysis and reliability prognosis of Photovoltaic Inverters. The VTB usefulness and versatility are demonstrated by way of the analysis and comparison of three inverters: full-bridge, T-type and I-type neutral-point configurations. Meteorological data from the intended installation site was used to develop a mission profile. The results include the Mean Time Between Failures, and both individual and overall failure rates. The VTB is a resource-saving alternative for performing reliability audits of the designs to be prototyped, providing valuable information that saves time in later design cycle stages.

针对光伏逆变器的综合虚拟测试台的开发

本文描述了一个全面的虚拟测试台 VTB 的实施，旨在对光伏逆变器的可靠性进行预测。该方案基于可靠性设计方法，并使用 FIDES 可靠性预测方法来包括有关任务概况的信息。这与选定的计算工具相结合，为光伏逆变器的分析和可靠性预测提供了一种快速、低成本的工具。通过分析和比较三种逆变器：全桥、T 型和 I 型中性点配置，证明了 VTB 的实用性和多功能性。来自预定安装地点的气象数据被用于制定任务概况。结果包括平均故障间隔时间，以及个别和整体故障率。
