The current trend is to go for more electric systems that rely extensively on power electronics such as EVs/HEVs and electric aircrafts, along with an increased use of renewable energy resources and variable speed motor drives. However, some field failure reports have revealed that power electronic converters represent the weakest point in these systems. A significant percentage of system failures are due to power electronic converter failures, which compromises systems reliability. This raises questions regarding the validity of relying on the current power electronic converter technology to run mission-critical/must-to-be-safe systems. Although power electronic converter technology has reached an advanced level in terms of efficiency, power density, and control, extra work should be done when it comes to reliability. Reliability engineering brings performing failure data analysis, accelerated life testing, lifetime prediction, and the implementation of efficient maintenance and reliability improvement schemes into an integrated process. This process is meant to enhance the reliability of a product throughout its life cycle. This paper provides an overview of the application of the key aspects of new approaches in reliability engineering for power electronic converters. The focus of this paper is on power switch bond-wire modules since they are the most vulnerable component in power electronic converters. This paper also proposes two general schemes for condition-based remaining useful lifetime (RUL) that are discussed in detail.

当前的趋势是寻求更多的电动系统，这些系统广泛地依赖于诸如EV / HEV和电动飞机的电力电子设备，以及对可再生能源和变速电动机驱动器的更多使用。但是，一些现场故障报告显示，电力电子转换器是这些系统中的最薄弱环节。很大比例的系统故障是由于电力电子转换器故障而造成的，这损害了系统的可靠性。这就提出了关于依靠当前的电力电子转换器技术来运行关键任务/必须安全系统的有效性的疑问。尽管功率电子转换器技术在效率，功率密度和控制方面已达到先进水平，但在可靠性方面仍需要做更多的工作。可靠性工程将执行故障数据分析，加速寿命测试，寿命预测以及有效维护和可靠性改进方案的实施整合到一个集成过程中。此过程旨在提高产品在整个生命周期中的可靠性。本文概述了新方法在电力电子转换器可靠性工程中关键方面的应用。本文的重点是电源开关键合线模块，因为它们是电力电子转换器中最易损坏的组件。本文还针对基于条件的剩余使用寿命（RUL）提出了两种通用方案，并对其进行了详细讨论。以及将有效的维护和可靠性改进计划实施到一个集成过程中。此过程旨在提高产品在整个生命周期中的可靠性。本文概述了新方法在电力电子转换器可靠性工程中关键方面的应用。本文的重点是电源开关键合线模块，因为它们是电力电子转换器中最易损坏的组件。本文还针对基于条件的剩余使用寿命（RUL）提出了两种通用方案，并对其进行了详细讨论。以及将有效的维护和可靠性改进计划实施到一个集成过程中。此过程旨在提高产品在整个生命周期中的可靠性。本文概述了新方法在电力电子转换器可靠性工程中关键方面的应用。本文的重点是电源开关键合线模块，因为它们是电力电子转换器中最易损坏的组件。本文还针对基于条件的剩余使用寿命（RUL）提出了两种通用方案，并对其进行了详细讨论。本文概述了新方法在电力电子转换器可靠性工程中关键方面的应用。本文的重点是电源开关键合线模块，因为它们是电力电子转换器中最易损坏的组件。本文还针对基于条件的剩余使用寿命（RUL）提出了两种通用方案，并对其进行了详细讨论。本文概述了新方法在电力电子转换器可靠性工程中关键方面的应用。本文的重点是电源开关键合线模块，因为它们是电力电子转换器中最易损坏的组件。本文还针对基于条件的剩余使用寿命（RUL）提出了两种通用方案，并对其进行了详细讨论。
