Abstract

fetched live from OpenAlex

This paper presents a high-efficiency soft-switching GaN-based single-phase inverter composed of a full-bridge DC-AC inverter and an auxiliary circuit. The auxiliary circuit incorporates two active switches and an inductor coupled with the filter inductor. The auxiliary circuit does not add any components in the main power path, and no isolated gate driver is needed. Besides, using a coupled-inductor in the auxiliary circuit reduces the voltage stress on the switches and enables the utilization of GaN switches. Moreover, a variable-timing method controls the auxiliary circuit and reduces the conduction losses in the auxiliary switches. As a result, the efficiency and power density are improved. The proposed inverter is analyzed, and experimental results of a 200kHz, 500W prototype converter are reported.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
