Description
Summary:	This paper presents the study and development of a processing power system to be used in the grid connection of renewable energy sources to the power grid. The system consists of a Zeta converter associated with a full bridge inverter operating at low frequency. The Zeta converter, operating in discontinuous conduction mode (DCM), plays the main role in this arrangement, producing a rectified sinusoidal current waveform synchronized with the electric grid. The full-bridge inverter, connected with the Zeta converter, provides de AC conversion inverting the current each half cycle. Initially it is presented the analysis of the Zeta converter operating in DCM, as well as a design criterion. Finally, the control strategy and experimental results for the proposed system are presented and discussed.
