Integrated Hybrid Resonant DCDC Converters

This book provides a comprehensive, single-source on resonant switched-capacitor converters. It is written in the style of a handbook, with systematic guidelines, and includes implementation examples. The authors explore integrated hybrid resonant DCDC converters in order to achieve highly compact, energy efficient and cost-effective power management solutions in the growing fields of wearables and internet-of-things applications. They provide an introduction into hybrid converters as a new and promising converter class, which merges capacitive and inductive conversion concepts into one. Coverage ranges from fundamentals to implementation details, including topics such as power stage design, gate drive schemes, different control mechanisms for resonant operation and integrated passives.

• Introduces a new, multi-ratio resonant converter architecture, which enables lower switching frequencies and better passive component utilization;
• Discusses circuit block design for high efficiency of the power stage;
• Explores implementation details and concepts for integrated passives;
• Derives models, implements and compares to each other different control mechanisms.
