PV Module Maximum Power Point Tracker (MPPT) is a photovoltaic system that uses the photovoltaic array as a source of electrical power supply. Every photovoltaic (PV) array has an optimum operating point, called the maximum power point, which varies depending on cell temperature, the insulation level and array voltage. The function of MPPT is needed to operate the PV array at its maximum power ...

The main problem today is the shortage of energy and environmental pollution. These problems can be avoided by employing renewable energy schemes. The most common renewable energy resources include Wind Energy, Tide Energy, Solar Energy, Hydrogen Energy, Bio Energy, Terrestrial Heat Energy and Thermal Energy and so on. Pakistan is affluent in almost all these resources especially in Thermal Ene...

This paper considers selection of the suitable simulation model for solar panels [1]. Two models for silicon polycrystalline photovoltaic solar cells [2], [3] were analysed. The selection is made by comparing the Power vs. Voltage and Current vs. Voltage curves obtained from the simulation to those obtained experimentally. The goal is to identify if a simulation model gives correct information ...

The proposed converter operates in zero voltage switching ...

The most important component affecting the efficiency of photovoltaic power systems are solar panels. In other words, efficiency of these systems are significantly affected due to the being low efficiency of solar panel. Thus, solar panels should be operated under maximum power point conditions through a power converter. In this study, design of boost converter has been carried out with maximum...

A rational design strategy of novel fluorophores for luminescent down-shifting (LDS) application was proposed and tested in this paper. Three new fluorophores (1a-c) with specific intramolecular charge transfer (ICT) and aggregation-induced emission (AIE) characteristics were synthesized as LDS molecules for increasing the output short circuit current density (Jsc) of a CdTe solar cell. Photoph...

The utilization of photovoltaic energy becomes an important source of electrical energy with the advancement in power electronic technology. The dc-dc converters is one of inevitable part of renewable energy system, for connecting the PV panel to the grid or AC load through an inverter. MPPT (Maximum Power Point Tracking) maximizes the power production of the PV panel. The advantages of high st...

We installed solar panels and digital meteorological equipments whose electrical power is supplied using PV on July 13, 2011. Then, the relationship between the electric power generation and the irradiation, air temperature, and wind velocity was investigated on a roof at a university. The electrical power generation, irradiation, air temperature, and wind velocity were monitored over two years...

Photovoltaic (PV) systems with a battery back-up form an integral part of distributed generation systems and therefore have recently attracted a lot of interest. In this paper, we consider a system of charging a battery from a PV panel through a current mode controlled boost dc-dc converter. We analyze its complete nonlinear/nonsmooth dynamics, using a piecewise model of the converter and reali...

The effective actions of a scalar and massless spin-half field are determined as functions of the deformation of a symmetrically squashed three-sphere. The extreme oblate case is particularly examined as per-tinant to a high temperature statistical mechanical interpretation that may be relevant for the holographic principle. Interpreting the squashing parameter as a temperature, we find that th...
