Conventional voltage of (28V DC, 115V/ 400 Hz AC) in traditional electro-energy power system EPS (Electric Power System), used for the "classic" aircraft (civilian and military) do not meet the requirements of advanced on-board autonomous power systems ASE (Autonomous Electric Power Systems) in the context of a modern system of EPS and a power electronic power system PES (Power Electronics Systems). It is dictated first of all by the fact that the concept of a more electric aircraft obliges manufacturers to implement in modern aerospace advanced solutions, among others in the field of high voltage power HVDC (High Voltage Direct Current). The subject, and also the purpose of this paper is to introduce the theme of aviation in terms of power HVDC, making its analysis by creating a mathematical model and simulation in software environment of Matlab/ Simulink selected components of the system ASE (EPS, PES) in the context of architecture HVDC in the range of high voltage DC 540V DC (±270V DC), and 350V DC. In the final part of this paper we present the results obtained on the basis of simulations and conclusions in the field of innovative architecture HVDC power in line with the trend of more electric aircraft (MEA/ AEA)
