This paper presents the design of a 70 kVA GaN–based multilevel power converter (EMC filters comprised) with a power density and efficiency superior to 10 kW/kg and 98.5%for future More Electrical Aicraft (MEA) power drive systems. The order of magnitude of these parameters, not verified in other papers for a converter of this power, were reached thanks to the prec ise optimization of each component, such as input/output filters and forced-air heat sink. In addition, PCBs, drivers and current sensor weights were also taken into account in the final converter weight analysis.
