“…However, two additional switches are needed to control the connection between the motor windings and bridge arm midpoint, and complex programmable logic device control is required. Considering the failure mechanism of the power converters in MEA, a lifetime-based control method was proposed to optimize the system loading to delay the wear-out based failures in [110]. A reduction in the standard deviation of failures of about 44% was achieved, and three years of B 0.1 lifetime extension was obtained for the system, and the mean system lifetime was slightly increased.…”

This paper presents a review of the electrical and electronic technologies investigated in moreelectric aircraft (MEA). In order to change the current situation of low power efficiency, serious pollution, and high operating cost in conventional aircraft, the concept of MEA is proposed. By converting some hydraulic, mechanical, and pneumatic power sources into electrical ones, the overall power efficiency is greatly increased, and more flexible power regulation is achieved. The main components in an MEA power system are electrical machines and power electronics devices. The design and control methods for electrical machines and various topologies and control strategies for power electronic converters have been widely researched. Besides, several studies are carried out regarding energy management strategies that intend to optimize the operation of MEA power distribution systems. Furthermore, it is necessary to investigate the system stability and reliability issues in an MEA, since they are directly related to the safety of passengers. In terms of machine technologies, power electronics techniques, energy management strategies, and the system stability and reliability, a review is carried out for the contributions in the literature to MEA. INDEX TERMS More-electric aircraft, machine technologies, power electronics techniques, energy management strategies, system stability and reliability.

“…Furthermore, the capacitors lifetime expansion is explored in [27], [28] by interleaving the converters. Moreover, the systemlevel reliability enhancement in multi converter systems is performed by appropriately modifying the converters loading and shifting the device damages from high-stressed converter to the low-stressed one [14], [29].…”

This paper aims to incorporate the reliability model of power electronic converters into power system reliability analysis. The converter reliability has widely been explored in device-and converter-levels according to physics of failure analysis. However, optimal decision-makings for design, planning, operation and maintenance of power electronic converters require system-level reliability modeling of power electronic-based power systems. Therefore, this paper proposes a procedure to evaluate the reliability of power electronic based power systems from the device-level up to the system-level. Furthermore, the impact of converter failure rates including random chance and wear-out failures on power system performance in different applications such as wind turbine and electronic transmission lines is illustrated. Moreover, due to a high calculation burden raised by the physics of failure analysis for large scale power electronic systems, this paper explores the required accuracy for reliability modeling of converters in different applications. Numerical case studies are provided employing modified versions of the Roy Billinton Test System (RBTS). The analysis shows the converter failures may affect the overall system performance depending on its application. Therefore, an accurate converter reliability model is, in some cases, required for reliability assessment and management in modern power systems.

This paper proposes a long-term performance indicator for power electronic converters based on their reliability. The converter reliability is represented by the proposed constant lifetime curves, which have been developed using Artificial Neural Network (ANN) under different operating conditions. Unlike the state-of-the-art theoretical reliability modeling approaches, which employ detailed electro-thermal characteristics and lifetime models of converter components, the proposed method provides a nonparametric surrogate model of the converter based on limited non-linear data from theoretical reliability analysis. The proposed approach can quickly predict the converter lifetime under given operating conditions without a further need for extended, time-consuming electro-thermal analysis. Moreover, the proposed lifetime curves can present the long-term performance of converters facilitating optimal system-level design for reliability, reliable operation and maintenance planning in power electronic systems. Numerical case studies evaluate the effectiveness of the proposed reliability modeling approach.
