Stand for Testing of Bi - Directional Converters in Photovoltaic Systems.

The purpose of this paperwork is to present a developed an experimental stand for testing different kinds of bi - directional circuits, providing a work of a supercapacitors in renewable energy systems - photovoltaic systems. A simulation model has been created of the studied bi - directional converter. During combined operation between a supercapacitor and a battery there are mainly two kinds of wiring methods. In the first method the battery is working in buffer mode and the supercapacitor is connected to the bi - directional converter. The second method is when the supercapacitor is working in buffer mode and the battery is connected to the bi - directional converter [1, 5]. In this paperwork a renewable energy system build in the first method is studied. For testing different circuit kinds of bi - directional converters in photovoltaic systems, an experimental stand, described in this work, has been created. The information measuring system is realized by the softwer LabView. In the document a comparison between the simulation and experimental results has been made. [ABSTRACT FROM AUTHOR]
