Preliminary Design of Energy Storage System and Bidirectional DC-DC Converter for Aircraft application

International audienceGreen solutions have gained rapid popularity in transportation. The more electric aircraft is one of main challenges. This paper deals with the methodology of designing an electronic module able to move aircraft on-ground and recover taxiing energy. The preliminary design addresses a power density of 30 Wh/kg, 60 Wh/dm 3 , 2 kW/kg and 2,5 kW/dm 3 . The braking phase is nearly 30 s along with peak current up to 150 A. The energy storage unit is based on lithium-ion batteries whereas an interleaving converter appears a good candidate as an architecture to fit with the aeronautic constraints
