Maximum Power Point Trackers (MPPT) are quite required in order to maximize the extracted power from photovoltaic (PV) generators. Since the PV module output power depends on environmental conditions, the tracking algorithm must ensure velocity and accuracy. Traditionally, methods like Constant Voltage, Perturb and Observe (P&O) and Incremental Conductance (IncCond) are widely employed and the choice from one or other depends on static and dynamic tracking features. This paper presents a method… Expand
