Calculation and Analysis of the Strands Short-Circuit in Stator Transposition Bar for Large Generators

IEEE Access, 2019
The transposition of the stator bar is an important technique in the large generator design. Under the excitation of vibration and thermal effect, the insulation of strand is easily damaged, which leads to short-circuiting fault, and adversely impacts ...

Impact of Strain on Drain Current and Threshold Voltage of Nanoscale Double Gate Tunnel Field Effect Transistor: Theoretical Investigation and Analysis

, 2010
Tunnel field effect transistor (TFET) devices are attractive as they show good scalability and have very low leakage current. However they suffer from low on-current and high threshold voltage.

Improving photovoltaic response of poly„3-hexylthiophene…/n-Si heterojunction by incorporating double walled carbon nanotubes [PDF]

, 2006
Poly(3-hexylthiophene)/n-Si heterojunction solar cells were studied with and without incorporation of double walled carbon nanotubes (DWCNs) in the polymer layer. Performance of the device improves by manyfold by incorporation of DWCN. The authors report

Influence of short circuit conditions on IGBT short circuit current in motor drives [PDF]

2011 Twenty-Sixth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2011
Protecting the IGBTs against short circuit conditions is a critical aspect of the Industrial motor drive design. The SC (short circuit) conditions can occur in a variety of ways in an industrial environment. The SC applied across the motor drive terminals result in a different fault current profile than a SC that happens at the motor terminals or ...

Base drive for paralleled inverter systems [PDF]

, 1980
In a paralleled inverter system, a positive feedback current derived from the total current from all of the modules of the inverter system is applied to the base drive of each of the power transistors of all modules, thereby to provide all modules ...
