Power electronics devices are widely used in different fields and for different residential applications. The expansion of their field of applications is related to the knowledge of the device behavior and their practical performances. The renewable energy sources such as PV modules, fuel cells or energy storage devices such as super capacitors or batteries deliver output voltage at the range of around 15 to 40 VDC. A boost converter is used to clamp the voltage stresses of all the switches in the interleaved converters caused by the leakage inductances present in the practical coupled inductors to a low voltage level. This paper presents a dc-dc power converter integrated closed loop system to attain high stability factor in such a way to obtain in a single conversion stage. The maximum energy extraction from photovoltaic panels, battery charging and discharging dynamic control, and high voltage step-up also is operating with soft-switching capability. This review is mainly focused on high efficiency step-up DC/DC converters with high voltage gain. The results are obtained through Matlab/Simulink software package.
Keywords: DC–DC Power Conversion, Capacitor Modules, Interleaved Methodology, PI Controller
