The main objective of this research work is to develop a new low-cost isolated three-level ac-dc power converter topology with a reduced number of switches. Existing three-level converter topologies change ac power to dc...

Abstract In this paper, it is demonstrated that the efficiency and ability to transfer power to the load in three-coil wireless power transfer (WPT) systems are always higher than in equivalent four-coil ones. On the oth...

This paper addresses the coordinated operation between wind farms and reservoir hydropower plants in networks with weak transmission capacity. The joint operation of the energy sources is captured by a Virtual Power Plan...

A novel mesh-free methodology for the coupled magnetic field-circuit simulation of power transformers is presented in this paper. The proposed methodology employs equivalent models for the conductors and the iron core, w...

Numerous approaches have been developed to generate optical vortex beams carrying orbital angular momentum (OAM) over the past decades, but the direct intracavity generation of such beams with practical output powers in...

En este trabajo se analiza la conformación de un paisaje de dominación mediante la georreferenciación de mapas manuscritos y el traslado de la espacialidad colonial hispanocriolla desde el papel al terreno. La zona es...

Abstract In this paper, a configuration of a passive Q-switched Erbium-doped fiber laser (EDFL) using a Lutetium Oxide (Lu2O3) thin film as a saturable absorber (SA) is experimentally implemented to generate high pulse e...
