The availability of solar energy varies widely with ambient temperature and different atmospheric conditions and hence the maximum power point (MPP) of photovoltaic system (PV) system is not stable. Therefore, a maximum power point tracking (MPPT) controllers are needed to operate the PV at its MPP.

In order to make full utilization of photovoltaic (PV) array output power, which depends on solar irradiation and ambient temperature, maximum power point tracking (MPPT) techniques are employed. Among all the MPPT strategies, the Perturb and Observe (P&O) algorithm is more attractive due to its simple control structure. Nevertheless, steady-state oscillations always appear due to the perturbat...

This paper focuses on the comparative study of maximum power point tracking (MPPT) algorithm. It has been analysed with different combination of DC-DC converters. Due to poor efficiency of Photo voltaic (PV) systems some MPPT methods are proposed. All MPPT methods follow the same goal that is maximizing the PV system output power by tracking the maximum power on every operating condition. In th...
