This paper shows the implementation and some industrial certification tests of a power equipment prototype designed to correct sags and swells, a dynamic voltage restorer, which is one of the many possible solutions for voltage sags and swells problems Experimental results of a 75kVA prototype are shown both in laboratory and full load conditions, in a certification institution (IEE-USP). © 2011 IEEE.341-346engDynamic Voltage RestorerPower QualityPWM ConverterVoltage SagsVoltage SwellsCertification testsDynamic voltage restorersFull-loadPossible solutionsPower equipmentProduction lossSensitive loadsElectric lossesIndustrial applicationsPower electronicsVoltage stabilizing circuitsPower qualityTrabalho apresentado em evento10.1109/COBEP.2011.6085264Acesso aberto2-s2.0-84255188823
