The Research on Grid-Connected Photovoltaic Inverter Based on DSP

This paper proposes a two-stage structure solar inverter topology with maximum power point tracking capability. The control of the solar inverter is digitally implemented using Freescale DSP56F8346, the dedicated photovoltaic intelligent power modules is used for constructing the power stages. In the design process, the circuit component and its parameters are calculated. A prototype is built in the lab to verify the proposed system design. Experimental results show that the system meets the design requirements.
