Monitoring ON-Resistance of MOSFET Devices in Real Time for SVPWM-VSI With Direct Compensation
Bibliographic record
Abstract
One of the major causes for the operation failure and/or malfunction in a voltage source inverter is from power semiconductor devices, such as MOSFET and IGBT. Especially, under harsh operating environments, the power devices face various mechanical/thermal challenges, which can increase the equipment/device failure rate and cause unexpected interruptions and/or serious safety issues. This paper focuses on estimating the ON-resistance of the MOSFET/IGBT devices in real time while operating in space-vector pulsewidth modulation mode to monitor the status on power MOSFET/IGBT devices in real time, hoping that it can avoid those unexpected interruptions for safety. Since the increase in ON-resistance of the power MOSFET is identified as the fault signature, it is worthwhile to measure ON-resistance to prevent the output voltage distortions and the amplitude reduction from the set reference voltage in advance.

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.
