TGF-β1/IL-11/MEK/ERK signaling mediates senescence-associated pulmonary fibrosis in a stress-induced premature senescence model of Bmi-1 deficiency

Experimental and Molecular Medicine, 2020
To study whether TGF-β1/IL-11/MEK/ERK (TIME) signaling mediates senescence-associated pulmonary fibrosis (SAPF) in Bmi-1-deficient (Bmi-1−/−) mice and determines the major downstream mediator of Bmi-1 and crosstalk between p16INK4a and reactive oxygen ...

PLL-less SRF technique for operation of SAPF under unbalanced and distorted supply voltage [PDF]

, 2018
Shunt active power filter (SAPF) has been recognized as a feasible solution to current harmonics issues. In its controller, due to structure simplicity, synchronous reference frame (SRF) technique is best suited to be applied in generating reference ...

A Lyapunov Stability Theory-Based Control Strategy for Three-Level Shunt Active Power Filter

Energies, 2017
The three-phase three-wire neutral-point-clamped shunt active power filter (NPC-SAPF), which most adopts classical closed-loop feedback control methods such as proportional-integral (PI), proportional-resonant (PR) and repetitive control, can only output

Enhancing SAPF performance with VOC and SVM for electrical networks depollution

International Journal of Power Electronics and Drive Systems (IJPEDS)
This paper presents a significant enhancement in the filtering performance of shunt active power filters (SAPF) by leveraging the voltage oriented control(VOC) in combination with a three-level NPC inverter using space vector modulation (SVM). The VOC technique enables precise control of the SAPF by utilizing the orientation of the voltages, thereby ...
