“…However the non-isolated boost charger requires, as its name shows, a step-up or boost converter as this technique uses fuel cells as power source. These fuel cells exhibit low voltages and so the need for a boost converter [11]. The conventional non-isolated boost charging technique has many advantages as it has a compact size, a light weight, a low cost and a simple circuit.…”

“…The conventional non-isolated boost charging technique has many advantages as it has a compact size, a light weight, a low cost and a simple circuit. On the other hand this technique creates a high ripple current at the output which makes is not very used because of the effects of this current that may cause internal heating [11].…”

This paper presents a review on the charging techniques of the batteries, particularly the lithium polymer 'LiFePO4'. The lithium polymer entrusts some characteristics, which select it over the other types of batteries in usage. Basically, there exists one charging technique that is commonly used in the industries nowadays and it is known by constantcurrent constant-voltage technique (CC-CV). Nevertheless, thistechnique might unveil some drawbacks to the battery as a whole such as overvoltage, which can lead to shortened lifetime of the battery. This is why a battery management system has been developed to protect each cell of the battery. Moreover, it would be interesting to see if there are any other techniques, which might either replace or enhance the conventional technique. This paper will be assisted with equations and graphs illuminating and verifying our work.

<p><strong> </strong></p>Generally the switch mode power supply input voltage source is constant or shows insignificant little varieties.in any case, when fuel call used input source the last assumption is not valid. A fuel cell stack is give a details of low and not controlled DC output voltage, moreover, when the demanded current increases the output voltage becomes low in a nonlinear form; from now on, suitable controller is required to taken the previously mentioned issues. In this article, a normal current-mode controller is planned to using a joined model for an energy unit stack and a boost converter; besides, the resolving control method increasing the system stability and output voltage regulation.. The proposed energy system utilizes an energy component power (polymer electrolyte film fuel cell) and a boost converter passing on power of 900 W. the proposed controller execution for output voltage regulation by means of closed loop gain estimations and step load changes. What's more, a correlation amongst open-and closed- loop estimations is made, where the controller robustness is tried for vast load varieties and fuel cell stack output voltage changes are shows on simulation results.

Proton‐exchange membrane fuel cells have been established as a really promising technology, specially due to their high efficiency and scalability features, additionally to their low pollution emissions. In a typical topology, fuel cell module (FCM) is usually integrated into a hybrid power system, where the FCM is designed to satisfy the main power requirements and reduce the current ripple at the fuel cell output. In this framework, the aim of this paper is to analyze and design a sliding mode control (SMC) for a FCM based on an isolated phase‐shifted full bridge converter. This particular topology provides a high conversion ratio and attains a reduction of switching losses, which allow its application in low and medium power systems. From the control viewpoint, the proposed module represents a challenge due to the highly nonlinear behavior and wide operation range of the FCM, together with system parameter uncertainties and perturbations. To solve these issues, a second‐order sliding mode super‐twisting algorithm (STA) is proposed. As its main advantage, the STA reduces significantly the control chattering while preserving several features of conventional SMCs, such as robustness and finite time convergence. In order to analyze the zero dynamics stability, a Lyapunov study is proposed, taking advantage of its particular Liérnad‐type system structure. Finally, the designed algorithm is thoroughly analyzed and validated by computer simulation on a commercial 10‐kW FCM and compared to first‐order SMC.
