Abstract
-Testing digital controllers for power electronic systems in real-time using a real-time digital simulator presents a problem, due to the discrete nature of the controller outputs which are not necessarily in synchronism with the time-step of the simulator. Reducing the simulation time-step resolves the issues resulting from the lack of synchronism between the digital simulator and the hardware controller under test. The simulation time can be reduced by distributing the computational burden among a number of parallel processors. However, the reduction in time is not directly proportional to the number of processors due to the interprocessors communication overhead. However, the simulation time can be greatly reduced if the simulator's hardware is custom configured. This paper is an effort to introduce and develop a reconfigurable hardware simulator using FPGAs to simulate power systems that contains power electronic switching elements. The simulation time-step for this simulator is less than 100ns. A new time domain model for power electronic switching elements is also presented in this paper. The new model is very convenient for real-time simulation purposes due to its simplicity and the elimination of numerical oscillations associated with other models.

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 it
