Two-Stage Control for Small-Signal Modeling and Power Conditioning of Grid-‎Connected Quasi-Z-Source Inverter with LCL Filter for Photovoltaic ‎Generation ‎ [PDF]

open access: yesJournal of Operation and Automation in Power Engineering, 2021
Grid-connected inverter-based photovoltaic (PV) systems play an important role in Distributed Power Generation (DPG). For this application, quasi impedance source inverter is very suitable due to its ability to increase or decrease the output voltage of ...

Suppression of line voltage related distortion in current controlled grid connected inverters [PDF]

open access: yes, 2005
The influence of selected control strategies on the level of low-order current harmonic distortion generated by an inverter connected to a distorted grid is investigated through a combination of theoretical and experimental studies.

Two-level DPC strategy based on FNN algorithm of DFIG-DRWT systems using two-level hysteresis controllers for reactive and active powers [PDF]

open access: yesRenewable Energy Research and Applications, 2021
In this paper, a novel switching table (ST) of the twelve sectors direct power command (DPC) strategy of doubly-fed induction generator (DFIG) based dual rotor wind power (DRWP) is proposed using two-level hysteresis controllers for reactive and active ...

Rap1 binding and a lipid-dependent helix in talin F1 domain promote integrin activation in tandem. [PDF]

open access: yes, 2019
Rap1 GTPases bind effectors, such as RIAM, to enable talin1 to induce integrin activation. In addition, Rap1 binds directly to the talin1 F0 domain (F0); however, this interaction makes a limited contribution to integrin activation in CHO cells or ...

Classifying superconductivity in ThH-ThD superhydrides/superdeuterides [PDF]

open access: goldMaterials Research Express, 2020
Abstract Satterthwaite and Toepke (1970 Phys. Rev. Lett. 25 741) discovered that Th4H15-Th4D15 superhydrides are superconducting but exhibit no isotope effect. As the isotope effect is a fundamental prediction of electron-phonon mediated superconductivity described by Bardeen, Cooper, and Schrieffer (BCS) its absence ...

Tradeoffs between AC power quality and DC bus ripple for 3-phase 3-wire inverter-connected devices within microgrids [PDF]

open access: yes, 2011
Visions of future power systems contain high penetrations of inverters which are used to convert power from dc (direct current) to ac (alternating current) or vice versa.

THD and mucopexy: Efficacy and controversy

open access: yesAnnals of Medicine & Surgery, 2017
Transanal haemorrhoidal dearterialisation and mucopexy has evolved in recent years as a popular minimally invasive non-excisional surgery for symptomatic prolapsing haemorrhoids. The long-term outcome of this procedure however, remains to be established.

Three-phase Active Tracking AC-AC Voltage Regulator based on Buck Converter with an Efficient Hybrid Control Technique

open access: yesDüzce Üniversitesi Bilim ve Teknoloji Dergisi, 2022
This study proposes a switch-mode three-phase active tracking AC-AC voltage regulator based on the buck converter. The regulator topology incorporates a moderate number of components with less complexity and high efficiency.
