Half-Bridge Full-Bridge AC–DC Resonant Converter for Bi-Directional EV Charger
Bibliographic record
Abstract
A new topology and controller based on single-stage AC-DC resonant converter, without Electrolytic capacitors (E-cap), for bi-directional EV battery chargers is proposed in this paper. The topology is a Half-Bridge (HB)-Full-Bridge (FB) resonant converter with MOSFETs connected in series and in opposite direction on its AC Half-Bridge side plus an active filter on the DC-side. No use of E-cap makes the converter more reliable. The establishment of an appropriate control scheme enables a wide range of active and reactive power control under different AC and DC voltage levels. The proposed controller not only facilitates the converter to operate under Zero Voltage Switching (ZVS) for all switching instants, but also it minimizes the conduction loss. ZVS allows higher switching frequencies and together with reduction in conduction losses improve the efficiency. The active filter is controlled to absorb the low frequency current ripple and prevent it from going to battery. Charging the battery with reduced low frequency ripple prevents extra heat production and increases the lifespan of the battery. Mathematical analysis, simulation and experimental results are presented.

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.
