| Abstract: | The design of a single phase photovohaic grid-connected inverter system based on TMS320F2812 was presented. The constitute and designs of the software flow chart of MPPT, the inverter tracking control of power grid and the SPLL control of grid voltage were analyzed. Matlab based simula- tions for the inverter systems were carried out and a developed prototype was tested. Results showed the wave of grid connected current had the same frequency and phase as the utility voltage. The results con- finned the effectiveness of the inverter system. |
