Grid-connected photovoltaic systems utilize static converters which influence the efficiency of the system. The energy conversion depends on the architecture of the converter, different solutions are available and H-bridge multilevel converters seem to be an optimal solution also for the power quality. The present renewable energy development and use will trigger a fourth industrial revolution; of all the renewable energy use methods, photovoltaic power generation is a critical part of overall renewable energy development. According to the world energy organization predictions, as the traditional energy sources (such as coal, oil, and so forth) gradually dry up, renewable energy power generation will become a major energy method.
Distributed Photovoltaic Grid Transformers covers innovative research and techniques in the key design, operation, and maintenance aspects of transformers suitable for solar energy. Real life scenarios and case studies from around the world are included. Architecture is proposed that includes a Power Electronic Transformer which is practically an isolated high-frequency link AC/AC converter that substitutes a conventional transformer.
