Robust and affordable high-performance methods are also needed for isolated sites. This paper takes this approach, in which an AC switched reluctance generator is used as a generator with a variable rotor speed. Although the voltage obtained is of insufficient quality to connect the generator directly to the power grid, this kind of generator can be used in isolated sites to charge a battery bank with a simple bridge rectifier. Due to the nonlinear behavior of the machine with the position and current, along with the alternating nature of the current that circulates through its phases, the machine experiences cyclical energy transformations of a mechanical, electrical and magnetic nature. This paper analyzes these transformations for the purpose of providing guidelines for machine design and optimization as a wind turbine in isolated sites. info:eu-repo/grantAgreement/ES/MINECO/DPI2006-10148 info:eu-repo/grantAgreement/ES/MINECO/DPI2009-08040 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.262 2016 ENERGY & FUELS 45 / 92 = 0.489 2016 Q2 T2 0.662 2016 Electrical and Electronic Engineering 2016 Q1 Renewable Energy, Sustainability and the Environment 2016 Q2 Energy Engineering and Power Technology 2016 Q2 Control and Optimization 2016 Q2 Energy (miscellaneous) 2016 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-3302-7862 Perez Cebolla, Francisco José Universidad de Zaragoza (orcid)0000-0002-3643-2847 Martín del Brío, Bonifacio Universidad de Zaragoza (orcid)0000-0001-9334-4870 Bernal Ruiz, Carlos Universidad de Zaragoza (orcid)0000-0001-5664-7063 Bono Nuez, Antonio Universidad de Zaragoza 5008 785 Universidad de Zaragoza Dpto.
