The paper presents a Field Programmable Gate Array (FPGA) based tracker to accurately track the maximum power point (MPP) of a photovoltaic (PV) array. The tracking logic realized on FPGA is based on a modified version of Adaptive Perceptive Particle Swarm Optimization (APPSO) technique. Photovoltaic generation systems use MPP tracker because the photovoltaic array exhibits multiple maxima in t...

This paper deals with the study of different type of MPPT (Maximum Power Point Tracking) algorithms in a solar photovoltaic system (SPV) in order to extract maximum power from the solar modules. Here the solar array is integrated with the grid to provide power, as the traditional sources of power generation is depleting at a faster rate and also to provide power during peak hours in urban areas...

The output power induced in the photovoltaic modules depends on solar radiation and temperature of the solar cells. To maximize the efficiency of the system, it is necessary to track the maximum power point of the PV array. In this paper an application of sliding mode control strategy is applied to track maximum power of photovoltaic cells. In this control system, it is necessary to measure the...

We investigate the one-parameter Calabi-Yau models and identify families of D5-branes which are associated to lines embedded in these manifolds. The moduli spaces are given by sets of Riemann curves, which form a web whose intersection points are described by permutation branes. We arrive at a geometric interpretation for bulk-boundary correlators as holomorphic differentials on the moduli spac...

This paper deals with the determination of the nonlinear I–V parameters of the equation by adjusting the curve at three points: open circuit, maximum power, and short circuit.
