Harmonics in Power Systems and Filter Applications
Black Sea Journal of Engineering and Science, 2019 With the advancing technology, loads in the system have been varied. These loads are always asked to be linear. However, with the effect of progressive semiconductor technology, an increase in nonlinear loads has been observed in the system. Nonlinear loads are loads whose current and voltage characteristics are nonlinear.

A hybrid active filter for damping of harmonic resonance in industrial power systems [PDF]
, 1998 This paper proposes a hybrid active filter for damping of harmonic resonance in industrial power systems. The hybrid filter consists of a small-rated active filter and a 5th tuned passive filter.

Current injection-based modeling of passive and active power filters in OpenDSS
International Journal of Electrical Power & Energy SystemsThis study proposes active and passive filters based on current source models for use in power flow and harmonic flow studies. In a traditional power flow analysis, passive filters are modeled as impedance models incorporated into the bus impedance ...

Molecular Oncology, EarlyView.Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...
