Abstract
Bidirectional dual-bridge DC/DC converter with high-frequency isolation is gaining more attentions due to small size, high power density. In this paper, a dual-bridge series resonant DC/DC converter is analyzed with two simple ac equivalent circuit analysis methods for both voltage source load and resistive load. In both methods, only fundamental components of voltages and currents are considered. All the switches may work in either ZVS or ZCS for a wide changes in load or supply voltage allowing itpsilas use in a wide range of applications, such as renewable energy generation, regular battery charger/discharger, do motor control, etc. It is also shown in the second method that the load side circuit could be represented with an equivalent impedance. The polarity of cosine value of the load angle reveals the power flow direction. The analysis is verified with PSIM simulation results. Experimental results based on a 200 W prototype circuit are also included for validation purpose.

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 it
