Non-Isolated DC-DC Converters for Renewable Energy Applications

Photovoltaic (PV) energy generation is an excellent example of large-scale power generation through various parallel arrangements of small voltage generating cells or modules. However, PV generation systems require power electronic converters system to satisfy the need for real-time applications or to balance the demand for power from electric. Therefore, a DC-DC power converter is a vital constituent in the intermediate conversion stage of PV power. This book presents a comprehensive review of various non-isolated DC-DC power converters. Non-Isolated DC-DC Converters for Renewable Energy Applications presents the original investigation and scope to design new families of converters: DC-DC multistage power converter topologies, multistage "X-Y converter family", Nx IMBC (Nx Interleaved Multilevel Boost Converter) Cockcroft Walton (CW) Voltage Multiplier based Multistage/Multilevel Power Converter (CW-VM-MPC) converter topologies and Z source and Quasi Z source These all are discussed to show how they can achieve the maximum voltage conversion ratio by adapting the passive/active component in the circuits. For assessment, we have recommended novel power converters through their functionality and designs, tested and verified by numerical software. Further, the hardware prototype implementation is carried out through a digital processor, and the results always show a good agreement with basic theoretical hypotheses. This book offers guidelines and recommendation for future development with DC-DC converters in renewable energy applications based on cost-effective and reliable solutions.
