This paper demonstrates a topology-device selection and multi-objective optimization tool for a 350 V dc, 27 kVA aircraft inverter system. The design space is generated with the topology-device combination as the primary variable and the switching frequency as the secondary variable, which considers two-level vs. three-level topologies and Silicon (Si) vs. Silicon Carbide (SiC) devices. The proposed optimization tool conducts automated design of each component and estimation of their performances regarding power loss and volume/weight through a holistic approach, which bases on full analytical models that have been derived in literature and those with latest development. The proposed tool can rapidly and accurately show the multi-objective design trade-offs and inform the optimal design choices.
