Hybrid Inverters With Dual Switching Frequencies for Switched Reluctance Motors

open access: yesEnergy Science &Engineering, EarlyView.
A hybrid dual‐switching‐frequency inverter for SRMs is proposed, combining SiC and IGBT devices based on rotor inductance. The method enables accurate current tracking with simple hysteresis control, significantly reducing torque ripple, vibration, and acoustic noise while cutting inverter cost compared to full‐SiC solutions.
