The subject of the paper is to present innovative technological architecture of the power supply system EPS (Electric Power System) in the field of high voltage power HVDC (High Voltage Direct Current) by conducting a critical analysis of the literature as well as an analysis and simulation of its selected component in line with the trend of more electric aircraft MEA (More Electric Aircraft). The considered advanced technologies relate to the architecture of the power supply system HVDC in the high voltage 540V DC (±270 V DC) and 350 V DC, used for advanced aircraft in line with the trend of MEA/ AEA, in particular for military aircraft made by Lockheed Martin (F-22 Raptor, the JSF F-35). Based on the above, the simulation of sample components of the system architecture of high voltage power HVDC has been made, selected from the group of military aircraft in the area of more electric aircraft ’More Electric Aircraft’, which is mainly the domain of advanced military aircraft the JSF (Joint Strike Fighter) F-35 and F-22 Raptor. In the final part, the paper presents the main conclusions arising from the analysis and simulation of selected components of HVDC power system architecture in accordance with the concept of a more electric aircraft.

The purpose of this paper is to present some selected issues relating to the alternative application of the perspective concept on the plane board MEA (More Electric Aircraft), instead of the traditional solution, in terms of power (pneumatic and hydraulic systems). In the context of the analysis of this trend, particular attention is paid to the major advantages that aeroplanes have, made in accordance with the new technology and problems in autonomous systems of electricity generation (electric power grid of aircraft). Considering that the largest growth of the above trend of electric aircraft (MEA) applies to civil aviation, the most important role in this paper was assigned to civilian aircraft (Boeing, Airbus) in the context of power distribution in electro-energy systems. In addition, a review of air sources of electricity (electric power) generation was made for particular types of energy sources (generators, generator-starters, transformers, converters, etc.) and advanced on-board autonomous power systems ASE (Autonomous Electric Power Systems), used in most modern aircraft constructions (passenger and military aircraft). In the final part of this paper, based on a literature review of electric aircraft concepts (MEA) and a brief analysis, the main conclusions arising from the application of this trend in modern aviation are presented.
