Hegazkinen elektrifikazioa: aktuatzaile elektromekanikoak eta propultsio elektrikoa

Abstract

Nowadays, More Electric Aircrafts (MEA) are gaining attraction in order to achieve a more ecological, sustainable and ecient air transportation. In this context, traditional pneumatic, hydraulic and mechanical systems are being progressively substituted by electric systems. Two applications can be highlighted in MEAs: Electro Mechanical Actuators (EMA) and electric/hybrid propulsion. In this work, the state of the art of both applications is presented, showing experimental results obtained by the authors in a real EMA prototype. Additionally, the power electronics and electric machines that constitute such systems are studied, focusing on multiphase topologies that could meet the strict requirements of the aeronautical industry.
