This paper presents a comprehensive investigation of the performance of an electric drive powered by an asymmetric cascaded H-bridge multilevel inverter coupled with an interior permanent magnet synchronous motor (IPMSM). Different modulation strategies are evaluated and compared with a proposed hybrid technique to investigate the advantages of each method. Simulation results are used to assess dynamic behavior and harmonic performance, with a focus on total harmonic distortion and waveform quality. The findings demonstrate that the hybrid modulation approach achieves a better balance between efficiency and harmonic content, making it particularly well-suited for applications requiring rapid dynamic response and high-power quality, such as electric mobility.

Abstract
This paper presents a comprehensive investigation of the performance of an electric drive powered by an asymmetric cascaded H-bridge multilevel inverter coupled with an interior permanent magnet synchronous motor (IPMSM). Different modulation strategies are evaluated and compared with a proposed hybrid technique to investigate the advantages of each method. Simulation results are used to assess dynamic behavior and harmonic performance, with a focus on total harmonic distortion and waveform quality. The findings demonstrate that the hybrid modulation approach achieves a better balance between efficiency and harmonic content, making it particularly well-suited for applications requiring rapid dynamic response and high-power quality, such as electric mobility.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
