Reliability Testing of AlGaN/GaN HEMTs Under Multiple Stressors [PDF]

open access: yes, 2011
We performed an experiment on AlGaN/GaN HEMTs with high voltage and high power as stressors. We found that devices tested under high power generally degraded more than those tested under high voltage.

Transient voltage stresses in MMC–HVDC links – impulse analysis and novel proposals for synthetic laboratory generation

open access: yesHigh Voltage, 2018
To evaluate and optimise insulation coordination concepts for state of the art high-voltage direct current (HVDC) transmission systems, appropriate test voltage shapes are required for laboratory imitation of occurring stresses.

High voltage assisted mechanical stabilization of single-molecule junctions

open access: yes, 2017
The realization of molecular-based electronic devices depends to a large extent on the ability to mechanically stabilize the involved molecular bonds, while making use of efficient resonant charge transport through the device.

High Voltage

open access: yesManufacturing Management, 2020
Brexit pressures saw electric bike manufacturer, VOLT, open its first UK-based factory earlier this year – but the company hadn’t counted on the challenges of setting up shop during a global pandemic

Research on 3‐D total electric field of crossing high voltage direct current transmission lines based on upstream finite element method

open access: yesHigh Voltage, 2021
The ongoing large‐scale construction of ultra high voltage direct current projects in China makes the crossing of two high voltage direct current (HVDC) lines inevitable.

High voltage, please!

open access: yesNature Energy, 2017
Kesterite solar cells are low-cost alternatives for photovoltaics, based only on abundant metals, but they exhibit limited voltages. A new wide-gap kesterite solar cell provides a much higher voltage at a good efficiency.

A Short Ion Path High Voltage Tube [PDF]

open access: yes, 1938
A vacuum tube for the acceleration of charged particles is described. The total acceleration of the ions takes place in a distance of 18 inches although the total height of the tube is about 14 feet. It has been used at one million volts peak a.c.

A Quality Improvement Initiative to Standardize Pneumocystis jirovecii Pneumonia Prophylaxis in Pediatric Patients With Solid Tumors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric patients with extracranial solid tumors (ST) receiving chemotherapy are at an increased risk for Pneumocystis jirovecii pneumonia (PJP). However, evidence guiding prophylaxis practices in this population is limited. A PJP‐related fatality at our institution highlighted inconsistent prescribing approaches and concerns about

Study of Transformer Core Vibration Considering Magnetostrictive Anisotropy

open access: yesActive and Passive Electronic Components
Due to the influence of the magnetostrictive effect of silicon steel sheet, the core inevitably generates vibration in the working process of the transformer, and at the same time, there are differences in the magnetostrictive properties of silicon steel
