As well as many benefits, many conflicts arise with the large-scale connection of distributed generation (DG) in distribution networks. Leading the protection devices to malfunction and increasing the complexity of fault ...

This paper presents a fault detection and isolation (FDI) method for open-circuit faults (OCF) in the switching devices of a grid-connected neutral-point-clamped (NPC) inverter for photovoltaic (PV) applications. The ...

Asymmetric multilevel converters can optimize the number of levels by using H-bridges scaled in the power of three. The shortcoming of this topology is that the H-bridges are not interchangeable, and then, under certain ...

A strategy for fault detection and tolerance on the inverter that controls power flow in variable-speed permanent-magnet generators is proposed in this paper. The performance of the proposed strategy is analyzed in two ...

The Andean orogenic belt, located in the Central Andes "Pampean flat-slab" segment in northern Chile (27-29 degrees S), is composed of two major tectonic regions: the Coastal Cordillera and the Frontal Cordillera. To ...

We present the results of a series of analog models addressing the relationships between tectonic inversion and magmatism, taking the Lautaro Basin in northern Chile (27-28 degrees S), Central Andes as a natural case. The ...

This work presents contributions in the detection and identication of faults in multilevel inverters through the study of the converters behavior under these operation conditions. Basically, the approached fault consists ...

This work presents a comparison between methodologies used to detect and classify faults in tree-phase induction motors driven by frequency inverters. The applied method was the analysis of the current signals with stator, ...
