Power electronics has progressively gained an important status in power generation, distribution, and consumption. With more than 70% of electricity processed through power electronics, recent research endeavors to improve the reliability of power electronic systems to comply with more stringent constraints on cost, safety, and availability in various applications. This paper serves to give an overview of the major aspects of reliability in power electronics and to address the future trends in this multidisciplinary research direction. The ongoing paradigm shift in reliability research is presented first. Then, the three major aspects of power electronics reliability are discussed, respectively, which cover physics-of-failure analysis of critical power electronic components, state-of-the-art design for reliability process and robustness validation, and intelligent control and condition monitoring to achieve improved reliability under operation. Finally, the challenges and opportunities for achieving more reliable power electronic systems in the future are discussed. Index Terms-Capacitors, design for reliability (DFR), insulated-gate bipolar transistor (IGBT) modules, physics-offailure (PoF), power electronics, robustness validation. I. INTRODUCTIONP OWER electronics enables efficient conversion and flexible control of electric energy by taking advantage of the innovative solutions in active and passive components, circuit topologies, control strategies, sensors, digital signal processors, and system integrations. While targets concerning efficiency of power electronic systems are within reach, the increasing reliability requirements create new challenges due to the following factors:1) mission profiles critical applications (e.g., aerospace, military, more electrical aircrafts, railway tractions, automotive, data center, and medical electronics); 2) emerging applications under harsh environment and long operation hours [e.g., onshore and offshore wind tur-Manuscript

“…Analyzing the content of traditional textbooks, it has confirmed the absence of stated theory, and it also showed that the explanations of the mechanism of power conversion took the form of calculating the convertor properties. Basic content for power conversion also remained unchanged since the 1970's, during which definitions were provided on the concept of Power Electronics (4) . However, as the author has felt he has been unable to sufficiently explain certain phenomena throughout his authoring process of the text formerly, he has to explain something expounding these phenomena at the beginning of this work (1) .…”

Tung-Hai Chin * a) FellowThe theory for three types of power conversion is established. In a controlled rectifier circuit, the input poly-phase AC sources are switched and connected to the load one by one; thus, AC-DC conversion is established. This mechanism is referred to as power conversion by change of sources. On the other hand, in a DC-DC step-up chopper circuit, there is an interval when the input source supplies energy to a reactor and this reactor energy possessing its own direction is defined as electromagnetic momentum. After a switching action, in the next interval, the circuit begins to enclose the load and forms a current loop circulating through the source, reactor and load. Then, the electromagnetic momentum will force the current to flow into the load which is at a higher voltage than the source. The switch action will be repeated on and off, and the current loop will be changed accordingly; then, power conversion will be established and this mechanism is named as power conversion by change of loops. In addition, by using a four-quadrant switching device to change the source polarity, DC-AC conversion can be achieved, and this mechanism is defined as combined power conversion. Extensive discussions on the technical terms have also been undertaken, such as classification naming for the diode and the thyristor.

“…Power electronics is a field of electrical engineering that employs electronic circuits to convert and regulate electrical energy between different forms such as alternating current (AC) to direct current (DC) (rectifier), DC to AC (inverter), DC to DC (dc-converter), or AC to AC (ac-converter) [1][2][3][4]. It has numerous applications, including hybrid renewable energies [5][6][7], small-scale/large-scale storage systems [8][9][10][11][12][13][14], electric vehicles [15,16], and industrial automation [17].…”

This paper provides an overview of power electronics and its applications in various fields, emphasizing power conditioning and minimizing losses for high energy efficiency. It discusses the distinction between unidirectional and bidirectional converters and their applications in power systems. The significance of unidirectional and bidirectional power flow in different scenarios is explored. The importance of battery storage systems (BSSs) for grid stabilization, frequency regulation, and renewable energy integration is highlighted. The paper focuses on flexible active-reactive optimal power flow (A-R-OPF) frameworks in battery storage and power electronic systems, reviewing existing research, identifying gaps, and offering new perspectives. It addresses the challenges and potential of grid-scale energy storage for reliable and cost-effective power systems with high renewable energy penetration. The need for energy curtailment, demand response, and smart grid implementation is discussed. The paper emphasizes comprehensive coordination, new power lines, European collaboration, and smart grid implementation to meet the dynamic needs of Europe’s power grids.
