The electrification of the transportation has shown a steady growth in the past decades. The unmistakable advantages of the electronics in terms of control capabilities, precision and the potential to reduce the pollutant emissions have been fueling this trend. The air transportation is now facing an unprecedented electrification push in The attempt to increase the aircrafts efficiency and reliability. Commercial aircrafts like the Boeing 787 and the Airbus A380 already show an overall electrical power in the MW range. In the meantime, concepts like hybrid propulsion aircrafts started to become a research reality. In this framework, the power electronics is of paramount importance to ensure an efficient and reliable power distribution and utilization. This manuscript reviews the power electronics solutions for the electrical power distribution systems. Particular attention is given to the promising technology of multiport DC/DC power converters, whose functionality is shown with a converter prototype.
