“…This study attempts to focus on recent techniques proposed since the review performed by Yang et al in 2010 [12], and the study simultaneously is more concentrated on online CM methods, which can be employed in real-time operation of the power converters. The CM definition can be explained that the technique targets tracking variations in the electrical parameters that are an indication of device degradation or incipient fault [20]. Because monitoring all of the electrical parameters is not practicable in a power converter, specific parameters should be recognized depending on the dominant aging failure mechanism.…”

As one of the most vulnerable components to temperature and temperature cycling conditions in power electronics converter systems in these application fields as wind power, electric vehicles, drive system, etc., power semiconductor devices draw great concern in terms of reliability. Owing to the wide utilization of power semiconductor devices in various power applications, especially insulated gate bipolar transistors (IGBTs), power semiconductor devices have been studied extensively regarding increasing reliability methods. This study comparatively reviews recent advances in the area of reliability research for power semiconductor devices, including condition monitoring (CM), active thermal control (ATC), and remaining useful lifetime (RUL) estimation techniques. Different from previous review studies, this technical review is carried out with the aim of providing a comprehensive overview of the correlation between various enhancing reliability techniques and discussing the corresponding merits and demerits by using 144 related up-to-date papers. The structure and failure mechanism of power semiconductor devices are first investigated. Different failure indicators and recent associated CM techniques are then compared. The ATC approaches following the type of converter systems are further summarized. Furthermore, RUL estimation techniques are surveyed. This paper concludes with summarized challenges for future research opportunities regarding reliability improvement.

“…At the component level, [5] gives an overview of reliability factors of various types of capacitors, and a design approach is proposed to improve the capacitor reliability. In [6], authors focus on power semiconductor devices, and reliability aspects of such devices in converter applications are reviewed. At the system level, [7] presents an approach where the reliability of the overall system can be improved if spare components are provided for some specific system elements.…”

<p>Modular Multilevel Converter (MMC) is favorable for high-power grid-connected power electronic applications to achieve efficient operation. The required number of components significantly increases when higher modularity is introduced for the given voltage level, thus reducing the system reliability. This paper suggests a Mixed Redundancy Strategy (MRS) that combines the operational concepts using active and redundant spare sub-modules. It is shown that more than 50\,\% higher $B_{10} = 10 $ lifetime is achievable as compared to reliability improvement using Fixed-Level Active (FL-ARS), Load-Sharing Active (LS-ARS), and Standby Redundancy Strategy (SRS) with the same number of redundant submodules. The trade-off between operational efficiency and investment cost is explored to define the boundary for selecting MRS over other redundancy strategies with varying dc-link voltages and average converter loading considering a 10-year payback period and equivalent $B_{10} = 10 $ lifetime. The results are discussed for two case studies using load profiles adapted from available data from a medium voltage substation. The change in viability boundary for MRS is established with increasing $B_{10} = 10 $ lifetime and its sensitivity to power electronic component cost as well as assumed failure rate.</p>

“…Moreover, the converter reliability can be improved within operation using appropriate techniques such as adaptive switching frequency [7], advanced switching techniques, reactive power routing [13], [14] and preventive maintenance and active power sharing [15]. Furthermore, condition monitoring and fault diagnostics during operation can help enhancing the reliability of converters [16]- [18]. Moreover, power routing among converters based on their thermal stresses or loading conditions can have remarkable impact on the system reliability as it can dynamically distribute the thermal damages of the converters among them [14], [15], [19].…”

This paper proposes a power routing approach for active asset management in power electronic-based power systems. The proposed approach aims to expand the lifecycle of power converters as the key assets of modern energy systems. Moreover, it takes into account the operational costs of converter-based generation units in order to obtain economic dispatch in the system. As a result, the useful lifetime of converters is enhanced, thus improving the overall reliability of the system with respect to the operational costs of the generations. A numerical case study on a DC distribution system is presented to illustrate the effectiveness of the proposed approach.
