Abstract

fetched live from OpenAlex

A multiport converter topology suitable for renewable energy applications is presented with bidirectional power transfer capability for all its ports. The converter uses two differentially operated inverters and consists of two DC ports and an AC port. The multiport functionality is made possible through the use of a center tapped grid interface transformer which uses DC flux cancellation to prevent saturation of the transformer core during power transfer between the two DC ports. However, there is no penalty in terms of component ratings for either the transformer, filters or the semiconductors for power transfer between the main DC port and the grid or the auxiliary DC port. A control scheme that enables decoupled power transfer capability between ports is also presented. Both the proposed topology and the control scheme are validated through extensive simulation and experimental results for a 4 kW 400Vdc/200Vdc/208Vac system.

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.
