چکیده
The need for a cleaner environment and the continuous increase in power demands makes decentralized renewable energy production, like solar and wind more and more interesting. Decentralized energy production using solar energy could be a solution for balancing the continuously-increasing power demands. This continuously increasing consumption overloads the distribution grids as well as the power stations. Therefore having negative impact on power availability, security and quality. The efficiency and reliability of single-phase PV inverter systems suffers from new problems related to leakage current and safety. This problem can be reduced by using transformerless inverter topologies. The work presented in this paper deals with analyzing and modeling of transformerless PV inverter systems regarding the leakage current phenomenon that can damage solar panels and pose safety problems.

Photovoltaic systems integrated to the grid have received considerable attention around the world. They can be connected to the electrical grid via galvanic isolation (transformer) or without it (transformerless). Despite making galvanic isolation, low frequency transformer increases size, cost and losses. On the other hand, transformerless PV systems increase the leakage current (common-mode c...
