In this paper, new design optimization techniques focused on transformerless (very high efficiency) PV inverters are proposed. They have been developed based on an analysis of the deficiencies of the current, state-of-the-art PV inverters design technology, which limits the amount of PV energy supplied into the electric grid. The influences of the electric grid regulations and standards and the PV array operational characteristics on the design of grid-connected PV inverters have also been considered. The simulation results verify that the proposed optimization techniques enable the maximization of the PV energy injected into the electric grid by the optimized PV installation.http://creativecommons.org/licenses/by/4.0/691 - 69826th Annual IEEE Applied Power Electronics Conference and Exposition Koutroulis Eftychios Κουτρουλης Ευτυχιος Blaabjerg, Frede Institute of Electrical and Electronics Engineers Photovoltaic energy systems Photovoltaic facilities Photovoltaic power plants Photovoltaic solar generating plants Power plants, Photovoltaic Power systems, Photovoltaic photovoltaic power systems photovoltaic energy systems photovoltaic facilities photovoltaic power plants photovoltaic solar generating plants power plants photovoltaic power systems photovoltaic
