An Inductive Pick-Up for Beam Position and Current Measurements [PDF]

open access: yes, 2003
An Inductive Pick-Up (IPU) senses the azimuthal distribution of the beam image current. Its construction is similar to a wall current monitor, but the pick-up inner wall is divided into electrodes, each of which forms the primary winding of a toroidal ...

Optimization Design Study of a Full-Range Charged Calibration Device for a Low-Voltage Current Transformer

open access: yesEnergies
According to standards, the harmonic content should be less than 5% at the time of calibration, while the calibration index proposed in this paper stipulates that the primary current amplitude of 1%~120% of the full range of the accuracy level reaches 0 ...

Sub‐Nanometer Cobalt on Tungsten Titanium Carbide MXene (W2TiC2Tx): An Electrocatalyst for Highly Efficient and Stable Alkaline Hydrogen Evolution at Industrial‐Scale Current Density

open access: yesAdvanced Materials, EarlyView.
A novel W2TiC2Tx MXene prepared through a MAX‐phase route supports sub‐nanometer Co for highly efficient alkaline hydrogen evolution. Strong Co–W interfacial interactions optimize hydrogen adsorption and catalytic activity, enabling low overpotentials of 63 mV at 10 mA cm−2, small Tafel slope of 44.3 mV dec−1, and exceptional durability at industrially

Leakage Inductance Effects of Output Transformer on Current-Resonant Parallel Converter Characteristics

open access: yesIEEE Translation Journal on Magnetics in Japan, 1991
The effects of leakage inductance of the output transformer of a current-resonant parallel converter on the latter's characteristics were studied through simulations and experiments. As a parasitic resonance appears between the leakage inductance and the resonance circuit capacitor during the commutating period of the output rectifying circuit every ...

Engineering Metal‐Pocket Cooperativity in Single‐Atom COF Nanozymes for Selective Cascade Catalysis

open access: yesAdvanced Materials, EarlyView.
A multilevel programming strategy is developed to engineer single‐atom COF nanozymes with tunable metal centers and chiral pockets inspired by heme–pocket cooperativity. This approach enables controlled metal–pocket interplay for asymmetric cascade catalysis, delivering high activity, selectivity, and recyclability in an asymmetric oxidation–aldol ...

A light Darwin implementation of Maxwell’s equations to quantify resistive, inductive, and capacitive couplings in windings

open access: yesAIP Advances
High operating frequency is an enabler of high key performance indicators, such as increased power density, in electrical machines. The latter enhances the cross-coupling of resistive–inductive–capacitive phenomena in windings, which may lead to ...

Photolithographic Patterning of Colloidal Quantum Dots Enabled by Plasma‐Induced Ligand Polymerization

open access: yesAdvanced Materials Technologies, EarlyView.
Plasma‐induced ligand polymerization on colloidal quantum dots (QDs) renders them resistant to organic solvents, enabling conventional photoresist‐based photolithography. This approach achieves microscale patterning with feature sizes down to 3 µm, preserving the optical properties of the QDs and offering a simple and scalable route for QD‐based ...
