Optimized SHE-PWAM with Maximum Harmonic Elimination and Minimum Switching Frequency for PEC9 Inverter
Bibliographic record
Abstract
This article introduces an Optimized SHE-Pulse Width and Amplitude Modulation (OSHE-PWAM) for single-DC source, single-phase nine-level Packed E-Cell (PEC9) to suppress maximum harmonic while switching frequency is minimized. PEC9 is a developed compact multilevel inverter based on the horizontal extension of capacitors to provide single auxiliary DC-bus and effective charging and discharging states for active capacitor voltage balancing. Based on the proposed OSHE, both switching angles and DC input voltage amplitude are considered as variable in the conventional SHE equations and new equations are developed to deal with maximum harmonic elimination. On the other hand, OSHE also handles capacitor voltage balancing by defining a symmetrical preprogramed output voltage waveform for establishing SHE equations. Simulation results are attained by Matlab-Simulink and confirm the excellent operation of the OSHE-PWM obtaining maximum harmonic elimination and achieving capacitor voltage balancing in PEC9 inverter while the switching frequency is minimized.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
