Abstract

In order to electrify
commercial passenger aircrafts with several MW propulsion power, voltages in
the kilovolt range are necessary. Since fuel cells show a soft output voltage characteristic,
a boost converter is essential. Within this paper a 3.6 kV fuel cell
DCDC-converter is presented that is based on 3.3 kV SiC-MOSFETs allowing
much higher light load efficiency and switching frequency than conventional
silicon IGBT solutions. The higher light load efficiency is an important
feature for long haul aircrafts since the maximum power is only needed for
take-off and climbing up to the cruising altitude. Within this paper, a single
phase setup is built-up, the electrical design is explained and efficiency
measurements are performed.
