Abstract

fetched live from OpenAlex

This paper presents an analysis of a Wireless Power Transfer (WPT) System using a buck-boost converter for voltage regulation with the objective of maximizing efficiency by reducing conduction losses and achieving zero voltage switching (ZVS). Unlike conventional buck-boost converter gain characteristics, the buck-boost converter cascaded with the receiver of a WPT system does not have a monotonically increasing gain curve and instead shows a concave characteristic. Thus, a required output voltage can be obtained with two different values of duty ratio of the buck-boost converter if the voltage gain required is below the maximum attainable gain of the system. This novel work will investigate which duty ratio will yield a higher efficiency at various switching frequencies of the transmitter by considering conduction losses and the ability to obtain ZVS. Discussion on coupling strength between coils and its impact on ZVS capability is also shown. Experimental results on a 5W, 5V output system with the two possible duty ratios are used to verify the analysis.

Teacher imitation

Not 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.
