Elimination of Leakage Current in PV Based Current Source Inverter
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
This paper deals with the implementation of four leg inverter to eliminate the earth leakage current. In the PV based system, some amount of leakage current induces on the inverter output terminals due to high switching frequency and electromagnetic interface problem, which inject the leakage current into output load side. To eliminate the leakage current in the conventional system an isolation transformer can be used. This increase the cost and size of the system and reducing the overall efficiency and lifespan of the inverter. An implementation of four leg inverter in solar power system the leakage current can be eliminate through neutral coupling system. There by increasing efficiency and lifespan of inverter. The effectiveness of this proposed system was verified through MATLAB simulation and small scale prototype model.
