Summary:

In recent years, multilevel topologies have been introduced to allow static converters of electrical energy to address medium voltage (series connection) or high current (parallel connection). The new degrees of freedom provided by these topologies are a potential source of improvement, but they also make the design process more complex. The author of this book shows how the concepts of vectorization and design masks can be used to help the designer in comparing different designs and making the right choices. The book addresses series and parallel multicell conversion directly and the conce
