Control strategy of mine-used LCL three-level static var generator

Gong-kuang zidonghua, 2020
In order to adapt to special environment of coal mine and reduce volume and quality of mine-used static var generator(SVG), LCL filter and three-level inverter were used as main circuit topology of mine-used SVG.

A Fault-Tolerant Control Strategy for Three-Level Grid-Connected NPC Inverters after Single-Arm Failure with Optimized SVPWM

Energies, 2023
Three-level NPC inverters have been widely used in grid-connected systems due to their superior performance compared with two-level inverters, but more switches lead to high fault probability.

Water-mass transformations in a neutral density framework and the key role of light penetration [PDF]

, 2008
A new formulation is proposed for the evaluation of the dianeutral transport in the ocean. The method represents an extension of the classical diagnostic approach for estimating the water-mass formation from the buoyancy balance.

A Modified Three-Level Neutral-Point-Clamped Converter for a Low Carrier Ratio

In the application of high power electric propulsionand high-speed motor drives, a very low switching frequencyusually is employed, thus it has a very low carrier ratio, which inturn results in the failure of the established voltage-balancingschemes in ...

Analysis of variation of neutral point potential in neutral-point-clamped voltage source PWM inverters [PDF]

, 2006
The authors present the analysis of the neutral-point potential variation of the neutral-point-clamped voltage source PWM (pulse-width-modulation) inverter (NPC-VSI) for AC motor drives and static VAr compensators (SVC).

A Novel Virtual Space Vector Modulation Strategy for the Neutral-Point Potential Comprehensive Balance of Neutral-Point-Clamped Converters

Journal of Power Electronics, 2016
A novel Virtual Space Vector (VSV) modulation strategy for complete control of potential neutral point (NP) issues is proposed in this paper. The neutral point potential balancing problems of multi-level converters, which include elimination of low frequency oscillations and self-balancing for NP dc unbalance, are investigated first.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...
