Design of Photovoltaic Generation Grid-Connected Inverter Based on DSP
According to characteristics of solar photovoltaic generation system, this paper presents a design of a single-phase photovoltaic grid-connected inverter about 1KW based on the digital signal processor TMS320F2812. This paper designs the algorithm of MPPT (Maximum Power Point tracking) and the algorithm of phase tracking according to its characteristics. The experiment is successful, and the output voltage wave of grid-connected inverter has the same frequency and phase with the grid voltage. The power factor of grid-connected inverter has reached to 0.99.
