Modeling and control of a three-phase isolated grid-connected converter for photovoltaic applicationsDOI: 10.1590/S0103-17592011000300001 Keywords: grid-connected, photovoltaic, converter, pv. Abstract: this paper describes the modeling and control of a three-phase grid-connected converter fed by a photovoltaic array. the converter is composed of an isolated dc-dc converter and a three-phase dc-ac voltage source inverter the converters are modeled in order to obtain small-signal transfer functions that are used in the design of three closed-loop controllers: for the output voltage of the pv array, the dc link voltage and the output currents. simulated and experimental results are presented.
