A MHz High Voltage Gain PV Micro-converter Featuring Extended ZVS operation and Continuous Input Current With Coupled Magnetics
Bibliographic record
Abstract
A MHz DC/DC micro converter with extended zero voltage switching turn-on and step-up voltage capability for PV energy applications is presented. The proposed converter consists of a boost converter integrated with a CL parallel resonant converter. An auxiliary circuit is employed to achieve soft-switching operation at all conditions, and its inductor is coupled with the boost inductor to reduce the size and weight of the overall system. This in turn, allows for duty cycle based maximum power extraction control to be applied to the boost switch. The operating frequency of the converter’s switches are on the order of mega-hertz to further decrease the size and cost of passive components. Theoretical analysis and the operating principles of the proposed converter is provided. Simulation results on a 1.06MHz, 200W and 380V-output converter are presented to highlight the merits of the proposed topology. Experimental results are provided on a proof of concept prototype to highlight the features of the circuit.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
