Dynamic Analysis of a Supercapacitor DC-Link in Photovoltaic Conversion Applications

open access: yesEnergies, 2023
In this work, a dynamic analysis describing the charge and discharge process of a supercapacitor for the DC-link between a photovoltaic source and a constant power load is presented. The analysis results in a complete nonlinear and dynamic model that can

Controlling internal barrier in low loss BaTiO3 supercapacitors [PDF]

open access: yes, 2009
Supercapacitor behavior has been reported in a number of oxides including reduced BaTiO3 ferroelectric ceramics. These so-called giant properties are however not easily controlled. We show here that the continuous coating of individual BaTiO3 grains by a
