一种单相并网光伏逆变器的直接最大功率点跟踪方法

A direct maximum power point tracking (MPPT) method for PV systems has been proposed in this work. This method solves two of the main drawbacks of the perturb and observe MPPT, namely: 1) the tradeoff between the speed and the oscillations in steady-state and 2) the poor effectiveness in dynamic conditions, especially in low irradiance when the measurement of signals becomes more sensitive to nois...
