A Minimum Power Loss Approach for Selecting the Turns Ratio of a Tapped Inductor and Mode of Operation of a 5-switch Bidirectional DC-DC Converter
Bibliographic record
Abstract
One of the most important aspects for the reliable operation of a DC Microgrid is the DC-bus voltage regulation within the system. For this, Supercapacitors (SCs) are widely used as auxiliary devices since they can provide sudden bursts of power and demand/supply currents with high gradients. Since commercial SCs usually present low voltage levels and, with the increasing trend of raising the DC-bus voltage, their connection in such systems requires power electronics interfaces capable of providing a wide range of voltage conversion. In this scenario, Tapped Inductors (TIs) provide a means for achieving low/high voltage gains in non-isolated DC-DC converters with neither too small nor too large duty cycles (D) by adjusting their turns ratio (n:1) to a desired value at a given operating point. However, a proper methodology for the actual choice of this value and the impacts of this on important aspects of the system, such as the converter efficiency, are still lacking in the literature. This way, this paper concerns a 5-switch DC-DC converter, based on a TI and that presents voltage gains that vary with D with Buck, Boost and Buck-Boost characteristics, where the main objective is to present an approach to determine the mode of operation and the turns ratio of the TI for reducing the losses on the power switches.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
