Editorial Special Issue on Power Electronics in Photovoltaic Applications, 2013

This Special Issue aims to address current challenges in the design and operation of Solar or photovoltaic (PV) energy systems, to report on novel ideas for enabling the wider utilization of PV energy and to explore optimal energy management control strategies for the PV-based Power Electronic System. The readers of this Special Issue will finally decide how well the previously stated goals are met. The accepted papers are not the only media by means of which the new ideas will be and have been promoted within the power electronics field. The most important media are actually the reviewers?? comments stating exactly, why the paper is rejected or the major/minor revision is needed, because they initiate the necessary mental processes in the authors and also in the reviewers leading finally sooner or later to the more comprehensive understanding of the topic area. This Special Issue received 151 original submissions of which 36 were accepted for publication at the time ofwriting this editorial. Acouple of submitted papers are still in the process and will be published later according to the normal publishing practices. Majority of the accepted papers (51%) are related to different design and control aspects of grid-connected single- and threephase inverters. The second largest category of papers (22%) is related to the maximum-power-point-tracking (MPPT) issues. The rest of the accepted papers are related to the implementation of distributed MPPT schemes (8%), the reliability issues in PV systems and converters (8%), the properties of PV generator, and other timely issues in the PV processing (11%); Ninety percent of the 151 papers were submitted during the last two weeks the submission opportunity was open.
