A half-bridge hybrid resonant inverter with novel pulse phase modulation control
Bibliographic record
Abstract
It is necessary that the phase angles of the inverter output voltages be controlled to minimize the circulating current in a high frequency AC (HFAC) power distribution system, where multiple resonant inverters are paralleled to the high frequency AC bus through connection inductors. However, the phase angle of the high frequency resonant inverters output voltage can not be controlled with conventional phase shift modulation or pulse width modulation. The phase angle is a function of both the phase of the gating signals and the impedance of the resonant tank. In this paper, we proposed a pulse phase modulation (PPM) concept for the resonant inverter, so that the phase angle of the resonant inverter output voltage can be regulated. The PPM can be used to minimize the circulating current in a multiple resonant inverter system. The mechanism of the PPM was explained and analyzed. The PPM-controlled resonant inverter was experimentally verified in two two-stage resonant inverters of 100W, 500 kHz.

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.
