Exploration of Inverter’s Efficiency and Lifespan at Various Phases of the Evolution using Wide Band Gap Power Devices

In any electric vehicle, electric motors and power electronic components, such as dc-to-ac converters, are essential. Improved electric machine and power electronic components efficiency may be achieved by novel materials, topologies as well as new control systems. During the study, the electromagnetic turbo compressors component for energy storage applications is fully explored. Strong single frequency as well as variable switching speed inverter is needed for the built electrical machine. The efficiency of the inverter and its expected lifespan at various phases of development are examined in this study. Power density and efficiency may be studied using both simulations and measurements throughout the design phase for wide band gap devices in discrete packaging. Surface-mount silicon carbide MOSFETs are used in the final design. By adopting three-level architecture instead of silicon devices, the power density of the inverter has been greatly boosted. Electrical and electronic devices have a finite lifetime because power semiconductors have a finite life cycle. It is possible to estimate the inverter’s lifespan depending on loss calculations and thermal gradients associated with virtual junctions.
