Smart Hybrid Active Power Filter Power Quality Improvement

International Journal of Advanced Research in Science, Communication and Technology, 2022
Filters are devices that remove undesirable or polluting particles from a required environment. Filters are used to ensure the purity of electrical power in electrical systems. Power filters are used to handle power quality concerns such as power factor, voltage stability, and harmonics.

Design and Implementation of Hybrid Active Power Filter

International Journal of Computer Applications, 2010
This paper deals with a hybrid active power filter with injection circuit (IHAPF). This paper concluded that the stability of the IHAPF based on detection supply current is superior to that of others. To minimize the capacity of IHAPF, an adaptive fuzzy dividing frequency-control method,.The generalized integrator is used for dividing frequency ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

An Improved Control Method of DC Voltage for Series Hybrid Active Power Filter

Energies
DC voltage is one of the important parameters of active power filters. Since the series hybrid active power filter does not withstand the fundamental voltage, it cannot absorb energy from the power grid, making it too difficult to control its DC voltage.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
