Towards High Efficiency Rational Switched-Capacitor Power Converter Topologies Slides

Abstract: With the advantages of higher-quality on-chip power components, fine system integrability and better loop stability, switched-capacitor power converters (SCPC) have attracted widespread interests in large-scale SoCs, low-power wireless integrated systems, and energy-harvesting-powered sensor microsystems. However, such applications typically require a high conversion efficiency in a small form factor as well as dynamic input/output voltage adaptation, inevitably raising the design challenges due to the diverse intrinsic limitations with the conventional SCPC topologies. This presentation will first review the key fundamental principles of SCPCs, together with the theoretical loss evaluation models. It will then introduce state-of-the-art rational topology designs and circuit implementations. The design tradeoffs among different rational topologies will also be introduced.
