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 ...

Single‐phase multi‐level AC–DC power conversion interface
IET Power Electronics, 2016 This study proposes a single‐phase multi‐level AC–DC power conversion interface that is composed of a power factor correction stage and a buck power conversion stage. The power factor correction stage is configured using two power factor correctors (PFCs) connected in cascade.

Novel topology of ac–dc converter using direct power conversion
IET Power Electronics, 2012 This study proposes a novel topology of the ac-dc converter using direct power conversion that has a simple structure and achieves high efficiency. The proposed converter is derived by integrating the step-down ac chopper and the output-voltage doubler. The proposed converter provides direct ac-dc conversion and isolated dc output voltage without using
