Abstract
The power-hardware-in-the-loop (PHIL)-based machine emulator systems use controlled power converters to mimic machine behavior. This testing method allows testing of the drive inverter and drive controller prior to the manufacture of an electric motor prototype. In this paper, a PHIL-based machine emulation system is used to mimic the behavior of a three phase induction machine (IM) which is connected to the grid. However, it is essential for the emulator inverter to have a dead time between the upper and lower switches. This dead time in the emulator inverter leads to lower order harmonics which deteriorate the motor emulation accuracy. Thus, it is important to investigate and analyze the effect of dead time in emulation. A detailed analysis of the dead time effect on motor emulation is presented. Experimental results are obtained from the emulator system and from a squirrel cage induction motor to validate the proposed emulator with various dead times.

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
