Study on different loading topologies of a six-phase self excited induction generator

Engineering Science and Technology, an International Journal, 2018
High number of phases of a multi-phase machine equip it with greater operational versatility. Due to the presence of dual 3-phases, a six-phase self excited induction generator (6φ-SEIG) is considered very convenient for grid connected as well as off ...

Common mode voltage elimination in dual-inverter-fed six-phase open-end winding PMSM drives with a single DC supply

The Journal of Engineering, 2019
This paper proposes a space vector pulse width modulation (SVPWM) technique to eliminate common mode voltage (CMV) and common mode current for dual-inverter six-phase open-end winding PMSM motor drive fed from a single DC supply.

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Single-Phase Rectifier with Cascaded-Transformer to Supply a Three-Phase Induction Motor with Open-End Windings

Eletrônica de Potência
This paper presents a single-phase to three-phase AC-DC-AC step-down converter with a symmetrical DC-link voltage ratio. The proposed converter architecture is well-suited for rural distribution grid applications, where a high-voltage single-phase grid ...

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

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 ...

Overmodulation Strategies for an Open-End Winding Induction Motor Drive With a Floating Capacitor Bridge

IEEE Transactions on Industrial Electronics, 2023
This paper considers a 3-phase induction motor with open-end windings fed by a primary bridge connected to the main power source and a floating bridge. The floating bridge supplies the motor with the required reactive power, while the primary inverter only exchanges active power with the main power source.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
