The new emerging aerospace applications such as electric propulsion need an increase of the embedded electrical power that necessitates increasing the voltage level in order to keep the current level in an acceptable range. Moreover, these new applications come with new electrical architectures and mission profiles that are very different compared to legacy aerospace ones. The currently available power quality standards in aerospace industry are limited to a voltage level of 270VDC (TBC) maximum and are not applicable to new high voltage propulsive networks. The task objective is to build the electrical requirements for higher voltage electrical networks that will be used to specify, develop and verify electrical equipment and systems that may be use for electrical propulsion.
