Hybrid Inverters With Dual Switching Frequencies for Switched Reluctance Motors
Energy 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.

Energy Science &Engineering, EarlyView.Turbulence intensity from 1% to 25% was parametrically tested on a three‐bladed H‐type Darrieus rotor across five tip speed ratios (TSRs) using two‐dimensional URANS. The optimal TSR proved the most efficient and most robust operating point simultaneously, with Cp losses capped at 5.8% even at TI = 25%. ABSTRACT The effect of inlet turbulence intensity

Energy Science &Engineering, EarlyView.SSA‐optimized fuzzy‐PI control reduces battery stress in flywheel–battery hybrid energy storage systems by shifting transient power fluctuations to the flywheel. The strategy decreases ampere‐hour throughput by 46.1% and rainflow damage by 71% while maintaining stable DC‐bus regulation.

Energy Science &Engineering, EarlyView.Three‐turbine guided Savonius arrays installed along highway corridors extract up to 697 J under multi‐vehicle wake conditions when spaced 12 rotor diameters apart—68% more than compact arrangements. Guide vanes boost output by 80–120%, and interior turbines respond most strongly to spacing, governing overall array performance. ABSTRACT Highway‐induced
