A Multiport Converter for More Electric Aircraft with Hybrid AC-DC Electric Power System
Bibliographic record
Abstract
More electric aircraft (MEA) use a heterogeneous combination of AC and DC power generation units and loads. As a result, the electric power system (EPS) of MEA is designed based on a combination of AC and DC voltages at different levels to increase the design's flexibility and improve energy efficiency. However, one of the main drawbacks of such architecture is that many power electronic converters are required to interface different voltage types, which increases system cost, size, and weight. This paper proposes a new multi-port converter to interface an AC distribution system to a high-voltage non-isolated, low-voltage isolated DC system. The isolated system is supplied through the high-frequency isolation transformer designed to operate at a fixed frequency. The proposed converter replaces two conventional AC-DC and DC-DC converters with only six active switches. Furthermore, the converter is operated by a well-known control method without adding complexity to the design procedure. The proposed converter's feasibility is verified with the simulation results obtained from a MATLAB/ Simulink model.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
