during this paper a completely unique topology for top increase DCDC convertor is introduced. The convertor makes use of coupled electrical device and voltage multiplier factor cell to achieve the specified high increase voltage gain. the most benefits of the projected convertor square measure easy topology, high increase voltage gain, continuous input current, exercise the energy of the run inductance of the coupled electrical device, and utilizing only 1 active switch with reduced voltage stress. Reduced switch voltage stress leads to choice of switch with low on-resistance that improves the potency. Operational principles of the convertor in steady state square measure studied Associate in Nursingd an analytical approach is employed to realize voltage gain and switch voltage stress.

In this paper, a photovoltaic (PV) generation system based on Hybrid Multilevel inverter is proposed. Hybrid multilevel inverter gives multilevel operation by using hybrid source, hybrid configuration or hybrid device in such a way to produce output with reduced number of DC sources, high speed capability, low output switching frequency, low switching loss, high conversion efficiency, exibility to enhance and various topologies for different applications. Simulations and analysis are done by the use of MATLAB/SIMULINK software. [ABSTRACT FROM AUTHOR]

The paper presents a non-isolated interleaved DC-DC converter with zero voltage switching. In modern power supply applications, the high voltage gain step-up DC-DC converters are widely used. These are fundamental conversion stages in electric vehicle and grid-connected renewables. Due to the low cost and high efficiency, it is not a trivial task. For this reason, the proposed method presented. It designed by a coupled inductor with active clamping to recycle the coupled inductor leakage energy. This model is capable of achieving more voltage gain without the need for extreme modulation signal. [ABSTRACT FROM AUTHOR]

Nowadays, environmental problems due to existing power plants seem to acquire more attention around the world, because it increases continuously the earth temperature and warming. Nowadays, renewable energies, especially photovoltaic (PV) energy, considered as palliative energy resource, are growing rapidly and are used in several applications, e.g., battery charging, home energy supply, and pumping systems. However, they suffer from a relatively low conversion efficiency, which makes their optimization necessary. This is done by extracting their maximum power for uctuating climatic environments. An efficient ANFIS based tracking algorithm is proposed for PV applications under mismatching conditions. PV fed zeta converter is used to step-up the output voltage and track the maximum power efficiently. An ANFIS based MPPT algorithm takes minimum time to find the MPP when subjected to rapid change in irradiance. [ABSTRACT FROM AUTHOR]
