摘要: This paper discusses a new implementation of perturbation and observation (P&O) maximum power point tracking (MPPT) algorithm that can mitigate/reduce the main drawbacks commonly related to P&O method. is achieved with peak current control, small values sampling instantaneous values, instead averaged, speed up system response reduce oscillations around (MPP). The number samples per switching cycle, type (synchronized/ unsynchronized) ideal instant for (maximum or minimum current) are investigated in order obtain fast calculation direction next perturbation. Experimental results proposed control scheme implemented DSP presented.
