Title: Stand for Testing of Bi – Directional Converters in Photovoltaic Systems Keywords: Battery, Bi – Directional converter, Labview, Abstract: 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. References Issue
