Abstract:
For the future integration of a multi functional fuel cell system “MFFCS” in “MEA” (more electrical aircrafts), weight and mass optimised power converters will be required. In such an application the converter connects the unipolar fuel cell system to a +/- 270 V bipolar High Voltage DC “HVDC” grid of the aircraft. In aviation, the system reliability and the system mass have higher priority than achieving highest possible system efficiency. Therefore, a power density optimised DC/DC converter for realiable operation within the harsh environmental conditions caused by high cooling temperature of the MFFCS has been developed.
