Analysis and Research of High-power IGBT Short-circuit Energy

open access: yes机车电传动, 2019
In view of the high-power IGBT short-circuit protection technology, the IGBT short-circuit reason and protective principle was introduced. The short circuit time of IGBT was verified to be closely related to its working voltage by short circuit test ...

Evaluation of Kapton pyrolysis, arc tracking, and flashover on SiO(x)-coated polyimide insulated samples of flat flexible current carriers for Space Station Freedom [PDF]

open access: yes
Kapton polyimide wiring insulation was found to be vulnerable to pyrolization, arc tracking, and flashover when momentary short-circuit arcs have occurred on aircraft power systems.

Short-circuit current improvement in thin cells with a gridded back contact [PDF]

open access: yes
The use of gridded back contact on thin silicon solar cells 50 micrometers was investigated. An unexpected increase in short circuit current of almost 10 percent was experienced for 2 cm x 2 cm cells.

A theoretical analysis of the current-voltage characteristics of solar cells [PDF]

open access: yes
The following topics are discussed: (1) dark current-voltage characteristics of solar cells; (2) high efficiency silicon solar cells; (3) short circuit current density as a function of temperature and the radiation intensity; (4) Keldysh-Franz effects ...

Process Research on Polycrystalline Silicon Material (PROPSM) [PDF]

open access: yes
Results of hydrogen-passivated polycrysalline silicon solar cell research are summarized. The short-circuit current of solar cells fabricated from large-grain cast polycrystalline silicon is nearly equivalent to that of single-crystal cells, which ...
