Understanding the Light‐Intensity Dependence of the Short‐Circuit Current of Organic Solar Cells
In organic solar cells, bimolecular recombination is a key factor limiting the device performance and creating the need for characterization. Light‐intensity‐dependent short‐circuit current density measurements are a frequently used tool to qualitatively

A Novel Fault Diagnosis Technique of Interturn Short-Circuit Fault for SRM in Current Chopper Mode
The interturn short-circuit fault of stator winding is a common failure mode in switched reluctance motors (SRMs), which can severely harm the operation of the motor. In this article, a novel method for diagnosing the interturn short-circuit fault in the

Characteristics of Short-Circuit Current in Distribution Network with Doubly-Fed Wind Power System
The doubly-fed induction generator (DFIG) is connected to the distribution network as a distributed power source, which turns a radial single power supply system into a dual power supply system and changes the topology of the distribution network. When a

Influence of the HTS Winding Tape on Limiting the Transient Currents in Superconducting Transformers
The article presents an extended computer model of a HTS (high temperature superconducting) 21 MVA 70/10.5 kV transformer with severalfold compound windings, based on a verified PSpice model of 10 kVA transformer with single windings. Two superconducting

Bidirectional Short-Circuit Current Blocker for DC Microgrid Based on Solid-State Circuit Breaker
In order to solve the imminent problem in that the traditional protection strategy cannot meet time requirements, together with the fact that the rotational inertia of a DC microgrid is small and short-circuit fault develops rapidly, a bidirectional ...

Equivalent modeling method of induction motor contribution to short-circuit current
When a short-circuit fault occurs in the power grid, induction motors in the distribution network will contribute to the short-circuit current. Accurate short-circuit current calculation of the motors requires detailed modeling of distribution network ...
