SwitchedCapacitor Converters (SCC) are preferred over inductor based switchmode regulators in low power applications that call for small size, or if the electromagnetic field radiated from the switched inductor may pose a problem. However, SCC suffer from a fundamental power loss deficiency that makes their use in some applications prohibitive. Losses can be reduced by applying soft switched SCC topologies that include an inductor. Another approach that has been recently investigated is SSC topologies with binary resolution that produce many "target voltages" of close proximity. This new SCC class is based on the properties of a novel Extended Binary (EXB) number representation. This seminar includes a comprehensive overview of present switched capacitor converters technology, covering both "hard switched" and "soft switched" configurations followed by indepth analysis and modeling of the causes of power losses. The review addresses step up, step down and inverting topologies as well as regulation methods. Finally, the concept and features of the new EXB sequences will be presented, backed by simulation and experimental results, and the rules for translating these sequences into SCC topologies will be detailed. The seminar is of intermediate level, intended for users and designers of switched capacitor converters. The seminar will cover, with many examples, the topics:
