Each MPPT method is analytically introduced and then it is simulated using MatLab/Simulink considering standard conditions of wind and also commercially available turbines and generators. The extracted power in each case is compared with the maximum available power, so the tracking factor is calculated for each method. Thus, the focus is on the application to improve the efficiency of stand-alone wind energy conversion systems (WECS) with battery chargers and AC load supplied by inverter. Therefore, for this purpose a novel single phase buck-boost integrated inverter is introduced. Finally, the main experimental results for the introduced inverter are presented. © 2011 IEEE.458-465engIntegrated Buck-Boost InvertersMPPT for small WECSRenewable Energy SourcesSmall WECS with PMSGWind EnergyAC loadBattery chargersBuck boost inverterBuck-boostComparative studiesIntegrated inverterMATLAB /simulinkMaximum available powerMaximum Power Point TrackingPermanent magnet synchronous generatorRenewable energy sourceSingle phaseStandalone applicationsStandard conditionsWind energy conversion systemElectric invertersEnergy conversionIntegrationPower electronicsSynchronous generatorsWind powerTrabalho apresentado em evento10.1109/COBEP.2011.6085307Acesso aberto2-s2.0-842552006326427185658143370
