Recent surveys reveal that impact of the electrical grid on specific global demands of energy is expected to climb 25% by 2040. It is a great hike, and the whole world is expected to increase its per capita income in a green and clean manner. To meet this requirement by using renewable generation, power electronics devices play a crucial role. The efficiency of the generation system greatly relies on converter topologies.
The paper focus on 1Ø grid linked inverter topologies that are not isolated. A comparison of four single-phase topologies is shown, including full bridge, H5, H6 and HERIC inverters. A discussion of topologies is carried out on the basis of common-mode voltage stability, leakage current, needs of the gate driver circuit, conduction loss and efficiency. The analysis presented assists to select appropriate inverter topology for a specific application in a PV system.
