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. 000048624 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/DPI2006-10148$$9info:eu-repo/grantAgreement/ES/MINECO/DPI2009-08040 000048624 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000048624 590__ $$a2.262$$b2016 000048624 591__ $$aENERGY & FUELS$$b45 / 92 = 0.489$$c2016$$dQ2$$eT2 000048624 592__ $$a0.662$$b2016 000048624 593__ $$aElectrical and Electronic Engineering$$c2016$$dQ1 000048624 593__ $$aRenewable Energy, Sustainability and the Environment$$c2016$$dQ2 000048624 593__ $$aEnergy Engineering and Power Technology$$c2016$$dQ2 000048624 593__ $$aControl and Optimization$$c2016$$dQ2 000048624 593__ $$aEnergy (miscellaneous)$$c2016$$dQ2 000048624 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000048624 700__ $$0(orcid)0000-0002-3302-7862$$aPerez Cebolla, Francisco José$$uUniversidad de Zaragoza 000048624 700__ $$0(orcid)0000-0002-3643-2847$$aMartín del Brío, Bonifacio$$uUniversidad de Zaragoza 000048624 700__ $$0(orcid)0000-0001-9334-4870$$aBernal Ruiz, Carlos$$uUniversidad de Zaragoza 000048624 700__ $$0(orcid)0000-0001-5664-7063$$aBono Nuez, Antonio$$uUniversidad de Zaragoza 000048624 7102_ $$15008$$2785$$aUniversidad de Zaragoza$$bDpto.
