The converter is fed by a multiphase high-speed/high-frequency permanent magnet generator. The main aim of the work is to demonstrate for the first time the feasibility of an MW-class generator system meeting future hybrid-electric propulsion requirements. A concept with multiple and isolated three-phase systems feeding different power buses is proposed to meet the availability requirements. Multiple converters (one for each three-phase system) are connected in series and/or in parallel to achieve the rated power and dc-link voltage. This article describes the key design concepts and the development and testing of the converter to meet the challenging application requirements. Reduced power tests are carried out on a full-scale 4 MW converter prototype, validating the proposed design. The work represents a step forward in terms of voltage, power, and output frequency with respect to the state-of-the-art. © 1982-2012 IEEE.enAerospace generation drivesHigh-power generation systemsHigh-power high-voltage converter designHybrid-electric aircraftMultiphase drivesVariable speed drivesArtículoAtribución/Reconocimiento 4.0 Internacional CC BY 4.0 Deed10.1109/TIE.2020.3040692
