This paper describes the research and development of a 3kV active rectifier for a 4MW aerospace generator drive system demonstrator. The converter is fed by a multi-phase high speed/high frequency, permanent magnet generator. The main aim of the work is to demonstrate for the first time the feasibility of a 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 paper 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.
