Abstract

This paper is proposed a novel topology of a single phase Grid connected Inverter in order to conquest the Common mode leakage current. There are many topologies presented so far, But none of them has the efficiency more than 98 percent. In this paper, a modern configuration is presented that, not only delete the Common mode leakage current, but also increase the efficiency and power density and is affordable. this inverter consists of 6 switches and 2 diodes that in compare with similar ones, it has less element number. Than the famous topologies like H5, H6 and HERIC, the power loss and voltage stress on switches are decreased. These aspects are appears due to exclusive leg configuration and the placement of switches and diodes. The freewheel path revealed, decoupled DC side from AC side of Inverter which results in disconnecting the common mode current. This issue will modify the network reliability indices and maintain safety standards. Finally the performances of proposed inverter will be compared and evaluated with some available Inverters.
