Abstract :
A practical photovoltaic (PV) cells model is applied to make a comparison of different maximum power point tracking (MPPT) methods. Then, the paper improves the constant voltage tracking (CVT) method and puts forward a higher tracking precision MPPT method. Its engineering realizing means is specifically introduced. At last, the paper analyzes the influence of PV cells resistance to MPPT precision.
