“…The above study of fault classification is valid for only an open‐circuit fault scenario. The short‐circuit fault causes unintentional conduction of faulty switch and it may lead to a shoot‐through condition across DC source and capacitor [29]. The possibility to convert short‐circuit condition into open‐circuit one confirms the tolerance ability of the proposed topology to all types of faults [28].…”

“…The topologies proposed in [20, 29, 30] generate the five‐level output voltage waveform, and thus, are precisely suitable for comparative analysis with the proposed topology. The topologies proposed in [29, 30] fail to deliver pre‐fault output power in case of multiple switch failure. Pradeep Kumar and Fernandes [24] have proposed a fault‐tolerant solution, which involves the implementation of the centre‐tapped transformer to maintain the same output power as in the healthy situation.…”

The redundancy in switching states to generate different voltage levels is of great importance to incorporate faulttolerant features in multilevel inverters. However, this redundancy comes at the expense of high device count, which is paralleled with vulnerable characteristics of semiconductor devices, resulting in low reliability. About this concern, the present study introduces a novel fault-tolerant topology to generate the five-level output voltage. The proposed topology can tolerate open-circuit failure, for single and multiple switches with the help of novel redundant leg architecture and short-circuit condition is dealt with the fast fuses. The comparative study with recent literature is discussed, which reveals the superiority of the proposed topology, in terms of qualitative as well as quantitative parameters. Switching strategies are proposed under different single and multiple switch fault cases, which achieves self-balancing of capacitor voltage. Thus, no complex control scheme is required. The simulation is performed in MATLAB/Simulink, and the feasibility of the proposed topology is validated using experimental results.

“…The equipped diode will continually work as a rectifier component when open‐circuit faults occur in one or more IGBTs. Except that the performance degrades such as output voltage fluctuation and current harmonics, the system will not crash immediately [23, 24]. Therefore, it is necessary to study the early fault features of three‐phase PWM rectifiers to get rid of safety hazards in time.…”

A three-phase pulse-width modulation (PWM) rectifier can usually maintain operation when open-circuit faults occur in insulated-gate bipolar transistors (IGBTs), which will lead the system to be unstable and unsafe. Aiming at this problem, based on random forests with transient synthetic features, a data-driven online fault diagnosis method is proposed to locate the opencircuit faults of IGBTs timely and effectively in this study. Firstly, by analysing the open-circuit fault features of IGBTs in the three-phase PWM rectifier, it is found that the occurrence of the fault features is related to the fault location and time, and the fault features do not always appear immediately with the occurrence of the fault. Secondly, different data-driven fault diagnosis methods are compared and evaluated, the performance of random forests algorithm is better than that of support vector machine or artificial neural networks. Meanwhile, the accuracy of fault diagnosis classifier trained by transient synthetic features is higher than that trained by original features. Also, the random forests fault diagnosis classifier trained by multiplicative features is the best with fault diagnosis accuracy can reach 98.32%. Finally, the online fault diagnosis experiments are carried out and the results demonstrate the effectiveness of the proposed method, which can accurately locate the open-circuit faults in IGBTs while ensuring system safety.

“…Six‐phase permanent magnet synchronous motor (PMSM) is widely used in aircraft, automobile and other new energy products in recent years due to its better fault tolerance capability and lower torque pulsations [1–5]. Compared with the traditional power system, the electric drive system has many advantages, such as simple structure, fast power response and quietness [6–8]. The purpose of the drive system's fault diagnosis is to more accurately and more efficiently reflect the fault‐tolerant performance of multiphase PMSM [9].…”
