Optimized Capacitive Filter Design in DC‐DC Converter Interfaces for Photovoltaic and Fuel Cell Systems

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper presents a methodology to design interface capacitive filters between renewable energy sources, such as photovoltaic systems and fuel cells, and DC‐DC converters. The proposal aims to reduce the volume resulting from the filter and improve the efficiency of the system. ABSTRACT This paper presents a methodology to design interface capacitive

Electrical Characterization and Modeling of a Gelatin/Graphene System

Advances in Condensed Matter Physics, 2015
A gelatin/graphene composite has been analyzed by means of current density-voltage and the electrical impedance measurements. The DC electrical behavior has been interpreted in terms of an equivalent Thévenin model taking into account the open circuit ...

Non-LTE line formation for heavy elements in four very metal-poor stars

, 2007
Stellar parameters and abundances of Na, Mg, Al, K, Ca, Sr, Ba, and Eu are determined for four very metal-poor stars (-2.66 < [Fe/H] < -2.15) based on non-LTE line formation and analysis of high-resolution (R ~60000 and 90000) high signal-to-noise (S/N >

X-ray Emission from the Binary Central Stars of the Planetary Nebulae HFG 1, DS 1, and LoTr 5

, 2010
Close binary systems undergoing mass transfer or common envelope interactions can account for the morphological properties of some planetary nebulae. The search for close binary companions in planetary nebulae is hindered by the difficulty of detecting ...

Abundances and Kinematics of Field Halo and Disk Stars I: Observational Data and Abundance Analysis

, 2000
We describe observations and abundance analysis of a high-resolution, high-S/N survey of 168 stars, most of which are metal-poor dwarfs. We follow a self-consistent LTE analysis technique to determine the stellar parameters and abundances, and estimate ...
