Proof of concept of 35 kW electrical taxiing system in more electrical aircraft for energy saving

In the More Electric Aircraft (MEA), many subsystems that previously used hydraulic, mechanical, and pneumatic power have been fully or partially replaced with electrical systems. Particularly, this article discusses feasibility of an equipment intended for electric taxiing application. Namely a 35 kW DC-DC converter 2500 Wh storage unit targets recovery energy from aircraft brake restitution on network. First, main technical characteristics prototype are described. The design battery pack is detailed. A interleaving multilevel appears to be good candidate fit aeronautic constraints. total mass such 68 kg while volume 72 L.
