Experimental Characterization of Filter Reactors for Grid-connected Solar Photovoltaic Systems

Abstract

This paper presents the magnetic characteristic measurements of filtering reactors for grid interface of photovoltaic systems. The standard procedure, generally used for this scope, is performed using different transient period in comparison with the conventional ones. The aim of this work is to show limitations and unsuitability of this procedure for some specific cases. A benchmark reactor with laminated FeSi core and suitable air gaps is presented and analyzed.
