Abstract—The usage of photovoltaic for solar energy conversion is a rapidly growing source of green power supply. Enhancing the efficiency of this system is widely seen as important in supporting this trend. This concerns not only the improvement of the PV cell but also of the power electronics circuits and controls associated to them. The various difficulties identified for the development of such a system is that discontinuous mode of conduction must be avoided and ripple content must be reduced. Therefore, in order to achieve this, an interleaved boost converter with maximum power point tracking based irradiance adaptive control is developed.
