Acesso em: 15 fev. 2019. 23524677http://www.repositorio.ufop.br/handle/123456789/10979This paper deals with the output voltage control problem of a three-phase three-wire voltage source Inverter (VSI) with LC output filter. A novel discrete-time active damping technique is proposed in order to damp the filter resonance without the need of current feedback. The method is based on an inner voltage feedback with digital lead compensator on the feedback path. A modified digital resonant controller is also proposed to reject the current harmonic disturbance drawn by nonlinear loads. The resonant controllers are connected in series and the design is based on its zeros damping. Results from a small scale experimental setup are used to validate the proposed control strategy.en-USrestritoVoltage source inverterActive dampingSingle voltage loop and modified digitalResonant controllerArtigo publicado em periodicohttps://www.sciencedirect.com/science/article/pii/S2352467718300092
