Abstract

fetched live from OpenAlex

AC machine drives with voltage-source inverters (VSIs) are extensively utilized in various applications. Average-value models (AVMs) of VSIs are used to facilitate fast and efficient simulations of such systems in electromagnetic transient (EMT) programs. However, the conventional existing AVMs do not consider losses in VSI operation. This paper presents a methodology to implement a lossy AVM (LAVM) and proposes three equivalent circuits for possible implementation. The LAVM considers conduction and switching losses, which also depend on operating conditions such as frequency and current. Depending on the LAVM interfacing needs, the losses may be implemented on the DC-side, AC-side, or split between DC and AC sides. The proposed methodology is demonstrated on an induction motor drive for which the losses are extracted experimentally and then fitted into the LAVMs. The proposed LAVM is shown to improve the accuracy of capturing the losses compared to the conventional detailed switching model and AVM of VSI driving the induction motor over a wide range of operating conditions.

Teacher imitation

Not 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.
