A non isolated type multi port inverter with minimum phase property and finely suppressed common mode leakage current for solar photovoltaic (PV) power processing is presented in this article. To avoid the limitations of solar PV based galvanically isolated systems like reduction of overall efficiency, increase in size and cost of the system this non isolated multi port inverter is proposed. However, these non isolated type solar inverters have limitation of flow of more dangerous common mode leakage current, when either it is connected to the grid or its neutral point is connected to the ground. The proposed non isolated multi port inverter is able to reduce the common mode leakage current well below the standard value. Further, the proposed non isolated multi port inverter is well capable to achieve minimum phase property unlike the boost converter.
