using photovoltaic systems is gradually expanded by increasing energy demand. abundance and availability of this energy, has turned to one of the most important sources of renewable energy. unfortunately, photovoltaic systems have two big problems: first, those have very low energy conversion efficiency (in act between 12 and 42 percent under certain circumstances). second, the power produced b...

Maximum Power Point (MPP) tracker has an important role in the performance of fuel cell (FC) systems improvement. Tow parameters which have effect on the Fuel cell output power are temperature and membrane water. So contents make the MPP change by with variations in each parameter. In this paper, a new maximum power point tracking (MPPT) method for Proton Exchange Membrane (PEM) fuel cell is pr...

Microbial fuel cells (MFCs) can be designed to combine water treatment with concomitant electricity production. Animal manure treatment has been poorly explored using MFCs, and its implementation at full-scale primarily relies on the bacterial distribution and activity within the treatment cell. This study reports the bacterial community changes at four positions within the anode of two almost ...

This paper presents a Maximum Power Point Tracking (MPPT) circuit in CMOS technology for integration into an energy harvesting solution, comprising a solid-state thinfilm lithium battery fabricated in the back-side of a plastic solar-cell. The MPPT CMOS circuit is required in the energy transfer process from the solar cell to the battery. The MPPT circuit was designed in the 0.7 μm CMOS process...

Photo voltaic based distributed generation system has seen a wide spread interest in research community because of growing energy needs. For efficient distributed generation system, a PV cell is connected with a DC-DC converter and DC-AC inverter. Maximum power point tracking (MPPT) algorithm is used to extract maximum power from the PV cell. There are different MPPT algorithms such as perturb ...

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...

A bunch of factors including the limited fossil resources and rising of fossil fuel price have been causes moving to create the new structure that is based on providing energy security, and protect the environment. One of the alternatives is the fuel cell (FC). Maximum power point tracker has an important role to increase the efficiency of the FC systems. One of the difficulties in maximum powe...
