Analysis and Design of Multicell DC/DC Converters Using Vectorized Models [Hardcover]

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 concepts can be generalized to describe other topologies.
