Abstract
To improve the conversion efficiency of the dual-active-bridge converter, this article demonstrates a variable-frequency triple-phase-shift (TPS) control strategy with the help of the deep reinforcement learning method. More specifically, the twin delayed deep deterministic policy gradient (TD3) algorithm is adopted to train the agent offline with the aim of minimum power losses, under the TPS modulation with varying switching frequency. Moreover, the zero-voltage-switching performance has been considered during the training of the TD3 algorithm. Based on these, the trained TD3 agent acts as a fast surrogate predictor, which can produce appropriate control strategies in real-time for whole continuous operating conditions with soft switching and maximum conversion efficiency. The effectiveness and correctness of the proposed scheme is validated through the experimental results in a laboratory prototype.

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
