Power conversion for a novel AC/DC aircraft electrical distribution system [PDF]
IET Electrical Systems in Transportation, 2014 This study proposes a novel and compact AC/DC electrical distribution system for new generation aircraft. In these new aircraft power systems, all loads are fed by two DC bus systems: at 28 V and at ±270 V. The electrical distribution system, whose design and implementation are described in this study, has only one primary AC source (360–900 Hz at 230 ...
