Abstract
In order to obtain more energy from photovoltaic cells during the inverse process, maximum power point tracking (MPPT) method is adopted in application. Common MPPT methods may cause misjudgment phenomenon, which not only reduce efficiency of PV energy conversion but also may cause grid-connected current distortion. To solve these problems, this paper presents an improved MPPT method and builds a two-level grid-connected inverter system based on MATLAB platform. Simulation result shows that the improved MPPT method could effectively obtain more energy from of photovoltaic cells, and improve the waveform quality of the grid-connected current.
