Abstract
Due to the continuous growth in air traffic, the concept of a More Electric Aircraft (MEA) is gaining importance. The aim of the MEA is to increase the electric load in an aircraft and eliminate traditional loads such as the mechanical, hydraulic and pneumatic loads. For this reason, this type of aircraft introduces several advantages such as weight reduction, reduction in fuel consumption and lower maintenance costs. In a MEA, several converters are required in order to obtain different voltage levels in the aircraft. This paper considers the operation of the Autotransformer Rectifier Unit (ATRU) for an Airbus A380 which converts 115V AC to 270V DC. A 12-pulse ATRU for a MEA was designed, modelled in Simulink/PLECS. Simulation results are given to validate the operation of the designed ATRU.
