“…It can be said that, in recent years, there has been much attention to redundancy structures in different circuits. For instance, different redundancy structures have been proposed for different converters: Inverters [70,71], the matrix converter [72], multilevel converters There are different researches in the field of power electronics reliability. In References [66,69], numerous redundancy structures and methods for improving the reliability of power electronic circuits have been assessed.…”

Abstract:The reliability of power electronic devices and components is very important to manufacturers. In recent years, many researchers have conducted reliability assessments of power electronic devices, yet the reliability of numerous circuits used widely has not been evaluated. This paper presents a comprehensive reliability evaluation of fundamental multilevel inverters. The reliability of the multilevel inverters is analyzed by calculating the mean time to failure for each component. The calculation was performed by two methods (approximate and exact) to achieve better comparisons. The approximate method is similar to the parts count method used in MIL-HDBK-217 reliability standard, and the exact method exhibits the parts stress method. In the exact method, due to the direct relationship between component failure and temperature, we used Matlab Simulink to determine power losses in diodes and switches taking into account the temperature factor. The results determined by the approximate method showed that the three-level cascade H-bridge was the most reliable of the inverters considered. Although the exact method validates those results, and shows that cascade H-bridge (CHB) had a longer lifespan, but the calculated values are different. Therefore, using different approaches for evaluating reliability results in different outcomes.

“…The modification introduced to the control strategy of the system under open phase fault condition is illustrated in Figure 3 [12][13][14][15][16][17]. First, in order to disable the switches in the faulty phase, the reference voltage of the faulty phase is set to zero.…”

“…Figure 1 shows the proposed fault-tolerant 2-level 4-leg converter drive topology [11][12][13][14][15][16][17]. In this topology, a fourth leg is added to the conventional 3-leg inverter and the redundant leg is permanently connected to the motor neutral point to provide the fault-tolerant capability in the case of an open phase fault.…”

Abstract:The behavior of Matrix Converter (MC) drive systems under the condition of MC short-circuit faults is comprehensively investigated. Two isolation strategies using semiconductors and high speed fuses (HSFs) for MC short-circuit faults are examined and their performances are compared. The behavior of MC drive systems during the fuse action time under different operating conditions is explored. The feasibility of fault-tolerant operation during the fuse action time is also studied. The basic selection laws for the HSFs and the requirements for the passive components of the MC drive system from the point view of short-circuit faults are also discussed. Simulation results are used to demonstrate the feasibility of the proposed isolation strategies.
