This comprehensive book delves into the intricate world of switched-capacitor DC-DC converters, offering a detailed analysis that reveals the key limitations and challenges faced by these converters. It establishes that these converters are primarily constrained by factors such as significant parasitic coupling, limited capacitor energy density, and the fixed voltage conversion ratio inherent in switched-capacitor converter topologies. To overcome these limitations, the authors introduce the concept of Advanced Multiphasing, a revolutionary approach that involves the integration of multiple out-of-phase parallel converter cores. Through this innovative technique, capacitor charging losses are minimized, leading to remarkable improvements in efficiency and power density.

The book showcases a range of techniques that leverage Advanced Multiphasing to achieve record-breaking efficiency and power-density levels. These techniques include phase-shifted modulation, parallel resonant charging, and cascaded H-bridge configurations. Moreover, the authors introduce a fundamentally new type of switched-capacitor topology called Continuous-Scalable Switched-Capacitor (CSSC). This topology allows for a continuously scalable conversion ratio, making it ideal for applications that require adjustable output voltage levels.

By providing a single-source reference to the Advanced Multiphasing concept, this book empowers readers with the knowledge and tools necessary to design DC-DC converters that harness the full potential of switched-capacitor technology. It enables them to explore the benefits of multiple converter cores, phase-shifted modulation, parallel resonant charging, and cascaded H-bridge configurations, ultimately leading to the development of highly efficient and versatile power conversion systems.

In conclusion, this book is a valuable resource for researchers, engineers, and students interested in the field of power electronics and DC-DC converters. It offers a comprehensive exploration of switched-capacitor DC-DC converters, highlights the limitations of traditional topologies, and presents innovative solutions through Advanced Multiphasing. With its practical insights and detailed explanations, it empowers readers to design and implement state-of-the-art power conversion systems that meet the demands of modern applications.
