ResumeCurrently, various systems and devices for on-board equipment of modern aircraft are undergoing extensive transformations, particularly in terms of powering electrified aircraft. The main goal of authors of this article was to conduct an analysis of the selected electrified aircraft architecture in the scope of the HVDC system, among architectures in the 540 V voltage range (± 270 VDC) and 350 V, creating a mathematical model and making the necessary tests and simulation studies on the developed model. In the above aspect, article presents selected test results of a proposed system consisting of aircraft generators with changing speeds, which power the bidirectional transistor converters operating in parallel. On the other hand, the energy, generated by generators equipped with a rectifier systems feeds a 0.4/15 kV booster transformer operating at idle. In the final part of the work, based on simulation studies (analysis, mathematical model, tests), important insights are presented and practical conclusions are formulated.

“…The development of the aircraft electric powertrain systems has evolved over the years, passing through many stages until achieving fully developed unmanned aerial vehicle (UAV) technology. The mechanical based speed drives such as constant speed drives (CSD) and integrated engine generator (IDG) is developed to provide mechanical interface with the 400 Hz synchronous alternator [3][4][5][6][7]. The mechanical coupling is essentially a variable ratio hydro-mechanical drive that coupled the jet engine shaft to the synchronous alternator through multiple gear stages and hydraulic cylinder block common to both the pump and the motor.…”

This paper presents a new electric powertrain for solar powered unmanned aerial vehicle (UAV). The proposed system structure is based on the development of the power supply system for both the Solong and Zyphyr aircraft models. The proposed UAV model incorporates the Zyphry UAV use of an AC line feeder instead of DC power lines to power the propellers. The proposed powertrain includes solar panels, an energy management system based on lithium sulfide battery, inverter, AC bus-line and active output filter (AOF). AOF topology is composed of a high switching frequency H-bridge inverter with a reduced size LC filter. The utilization of AOF system reduces the size and weight of the power transmission system and significantly improves its conversion efficiency by introducing an emulated series resistance with the Hbridge stage to ensure high quality pure sinusoidal waveform of the line voltage. This emulated series resistance produces an injected voltage across it to diminish unwanted harmonics created from the non-linear load. A simulation model and experimental setup are created to simulate the proposed system and the system is tested under non-linear load condition with closed-loop feed-back control strategy. The obtained simulation and experimental results demonstrate that high-quality sinusoidal line voltage waveforms can be obtained using the active resistance compensation technique with total harmonic distortion factor less than 3%. Moreover, power losses analysis and conversion efficiency calculation of the proposed system are performed and compared with that of the conventional three-phase PWM inverter, which proved that the power losses are reduced by 31%.
