| Abstract: | For the grid connected photovoltaic inverter, the maximal power point tracking（MPPT） is a key content for the design. This paper analyzes the physics and math model of PV array, presents several method of MPPT method and the modified CVT Perturbation and Observation method. The experimental results show that the MPPT design makes the PV array workin~ beside the MPP and the design is effective. |
