摘要
Grid-connected inverter is a key electrical unit for photovoltaic generation system. In this paper, the architecture and its advantages of a single phase photovoltaic grid-connected inverter based on DSP + ARM dual-core control are studied. The novel maximum power point tracking (MPPT) control based on extremum seeking control (ESC) algorithm is used in the proposed system, and the speediness and stability of MPPT are improved. By using efficient. reliable second-order generalized integral phase locked loop (SOGI-OSG PLL) control, the output current and the voltage frequency synchronism are realized well.
