Development of a mid-power core (35 kW) dedicated to inverters for aerospace applications

This paper presents the power core developed for the 70kW inverter dedicated for future aeronautical applications in the frame of the MOET program, a FP6 European Integrated Project [1]. Description, principle of operation and experimental results are presented. Considered as a major sub-assembly of the inverter, attention has been paid on the design and preliminary tests of the power core. Electrical, thermal, mechanical and EMC tests have been performed as a pre-qualification of the device. Inverter results have been already presented in [2] but specific power core results will be presented in this paper. For DC to AC conversion, technologies improvement and specific integration allow reducing weight and volume and increase the inverter power density for the first time up to 5kW/kg for the dedicated application.
