Résumé :
This seminar presents a novel approach for the Modulation technique applied on Asymmetrical Cascade H-Bridge Multi Level-Inverter (CHB-MLI) to improve its performance for motor drive applications, this approach is based on applying two modulation techniques in one algorithm : Staircase modulation technique and Selective Harmonics Elimination method (SHE) :
As a result, this algorithm will reduce the total harmonic distortion ratio with respect to the Norm IEEE-519. Furthermore, three study cases had been numerically implemented by SimScap / Matlab and validated under special conditions (varying modulation index and voltage disturbance on DC side).
