Power conversion for a novel AC/DC aircraft electrical distribution system [PDF]

open access: yesIET 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 ...

Single Power-conversion AC-DC Converter with High Power Factor

open access: yesThe Transactions of the Korean Institute of Power Electronics, 2014
This paper proposes a single power-conversion ac-dc converter with a dc-link capacitor-less and high power factor. The proposed converter is derived by integrating a full-bridge diode rectifier and a series-resonant active-clamp dc-dc converter. To obtain a high power factor without a power factor correction circuit, this paper proposes a suitable ...
