Short-Circuit Capability Prediction and Failure Mode of Asymmetric and Double Trench SiC MOSFETs
IEEE Transactions on Power Electronics, 2021In this article, short-circuit capability prediction and failure mode of 1200-V-class SiC MOSFET s with a double and asymmetric trench structure are proposed under single-pulse short-circuit stress. A short-circuit prediction model is established to evaluate short-circuit withstand time and corresponding critical energy of devices under various dc bus

AbstractA trade‐off between open‐circuit voltage (V OC) and high short‐circuit (J SC) becomes one of the most vital problems limiting further improvement in polymer solar cells' (PSCs) efficiency. In this work, two asymmetric polymer donors PBDT‐F‐2TC and PBDT‐SF‐2TC are designed and synthesized. When blended with a state‐of‐the‐art acceptor IT‐4F with

Three-phase three-leg inverter is one of the most popular topologies for inverters. When short-circuit fault occurs, the inverter is generally switched to the current-controlled mode from voltage-controlled mode to limit the fault currents. In this situation, the inverter becomes equivalent to a symmetric, three-phase, positive sequence current source.

Calculation of branch short circuit asymmetrical current considering breaking sequences
2021 IEEE 4th International Electrical and Energy Conference (CIEEC), 2021With the expansion of the scale of power grid interconnection, the grid connection is becoming more and more closely, and the grid resistance ratio is also increasing, which slows down the attenuation of the DC component of the short-circuit current, and affects the checking of the breaking capacity of the circuit breaker. At present, in practice, only

Analysis of breaking capability within asymmetrical short circuits
2015 16th International Scientific Conference on Electric Power Engineering (EPE), 2015This paper discusses the occurrence of asymmetrical currents and difficulties within their breaking due to the reduced breaking capability in limitary areas of breaker's characteristics. It's aimed at breaking of generator short-circuits with specific course.
