This paper deals with the fault tolerance analysis applied to the converter topology 5-level unidirectional T-Rectifier (5L T-RECT) to be used for electric generating applications. The proposed generating unit is intended for aerospace applications with high fundamental electric frequency, to this purpose the investigated power electronic converter configuration is able to supply power to the electric...
Thanks to the inherent redundancy to generate the different output voltage levels, the multilevel active-clamped (MAC) topology presents an important fault-tolerance ability which makes it interesting for several applications. This paper presents an analysis of the fault-tolerance capacity of the MAC converter. Both open-circuit and short-circuit faults are considered, and the analysis is carried...
The development of intelligent power grid provides a broad market to power electronic equipment. Compared with conventional transformer, intelligent solid state transformer(ISST) is pursuing smart control feature by power electronic converters and comprehensive controlling technology, which aims at voltage regulation, power transmission, isolation, and power quality improvement, etc. This paper analyzed...
A new topology of bridge-type SFCL, which can limit not only the rising speed but also the steady state value of fault current, is proposed in this paper. The new SFCL includes a bridge composed of 4 SCRs and 2 diodes, a superconducting coil and an ordinary bypass reactor. In normal status, the bridge works as a rectifier, the voltage across the coil is zero if the current of the coil keeps greater...
