Abstract :
This book presents advanced inversion technologies and provides design examples of inverters for renewable energy systems, including wind turbine and solar panel energy systems. The text systematically reviews cutting-edge inverter topologies and introduces new advanced topologies, originally developed by the authors, such as impedance source inverters (ZSI), quasi ZSI (qZSI), soft-switching inverters, and multilevel inverters up to 81 levels. Novel topologies include trinary hybrid multilevel inverters and four novel multilevel inverters: new series laddered multilevel converters, super-lift converter multilevel inverters, switched capacitor multilevel inverters, and switched inductor multilevel inverters. The authors also present modulation strategies and four methods to solve the problem of the accurate determination of the best switching angles to obtain lowest total harmonic distortion (THD) in advanced multilevel inverters. The analysis of the dc bus power injection is also presented, and methods to avoid regenerative power are also proposed. The text offers theoretical concepts, diagrams, summarizing tables, simulation and experimental results, and design examples for students, researchers, and engineers willing to learn from experts on how to design and implement inverters for renewable energy systems.
