This research aimed to investigate the effect of nanorice husk ash (NRHA) prepared using different thermal treatment methods on ultra-high-performance concrete (UHPC) behaviour. NRHA was prepared by two methods: (1) burning for 3 h at 300, 500, 700 a

This paper proposes a WECS based on a back to back diode-clamped multilevel inverter systems (DCMLI) fired comparatively by sinusoidal pulse width modulation (SPWM) and third harmonic injection pulse width modulation (THIPWM) techniques. DFIG perform

The proposed approach shows that the DCMLI systems generate a near sinusoidal voltage with reduced total harmonic distortion (THD). The power quality of the DFIG system is upgraded. A modified feedback control technique of DVR is pivotal to improve t
