Frequency Domain Analysis of a Wireless Power Transfer System Operating in a Wide Load and Coupling Range Using Frequency Modulation of Inverter for Voltage Regulation
Bibliographic record
Abstract
An accurate frequency domain analysis in the steady state has been introduced for a Wireless Power Transfer (WPT) system which maintains output voltage regulation by frequency modulation of inverter switches. The modelling has been shown for both continuous (CCM) and discontinuous (DCM) modes of operation considering harmonics on both sides of the resonant tank. This accurate analysis can be used for proper design and selection of system components such as the resonant capacitors, WPT coils and semiconductor devices. Two different characteristics of the system are identified based on the coupling coefficient between the transmitter and receiver coils and output load resistance range. Characteristic I, in which the inverter switches can be operated below the resonant frequency of the system to achieve zero-voltage switching (ZVS), is demonstrated in this paper for the first time. Experimental results on a 5W WPT system demonstrate the two different characteristics of the system and validate the accuracy of the analysis presented in this paper.

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.
