Reliability Analysis of a High-Efficiency SiC Three-Phase Inverter

Abstract: Abstract-Silicon carbide as an emerging technology offers potential benefits compared with the currently used silicon. One of these advantages is higher efficiency. If this is targeted, reducing the on-state losses is a possibility to achieve it. Parallel-connecting devices decrease the on-state resistance and therefore reduce the losses. Furthermore, increasing the amount of components such as parallel connection of devices introduces an undesired tradeoff between efficiency and reliability, since an increase… Show more

“…However, for conventional high-power, two-level converters, it is hard to increase the switching frequency, due to thermal management. Silicon carbide (SiC) based two-level voltage source converters (VSC) have emerged in recent years [7]. SiC is a wide bandgap material, which offers potential benefits including higher efficiency, higher switching frequency, and higher temperature operation.…”

“…The researchers in [18] focus on the effect of the redundancy of a Power Distribution Unit (PDU)-reliant system and prove that any failure in the PDU, which uses no redundancy, can cause the whole system to fail. According to [19], by adding a redundant switch to a silicon carbide (SIC)-based three-phase inverter, the MTTF of the inverter can be increased by approximately five times. Furthermore, [19] suggests making a trade-off between the efficiency and reliability in the studied high-power inverter.…”

Furthermore, [19] suggests making a trade-off between the efficiency and reliability in the studied high-power inverter. In [20], the reliability of the dc-dc converter utilized in a solar farm is studied, where the converters in solar farms deal with different power ranges, and thereby having different MTTF, are associated.…”

“…Additional research in the field of inverter design deals with increasing the efficiency of three-phase inverter based on SiC switches by using the parallel connection of power modules with the resulting reduction of the on-state losses as presented in [78]. A SiCinverter with a sinusoidal output filter is introduced with a compact Z-source converter in [79].…”
