ABSTRACT. This tutorial will cover the design, optimization and implementation of hybrid switched capacitor (SC) converters. First, a motivation for why hybrid SC converters are suitable solutions for power dense and efficient power delivery will be covered. A general introduction to hybrid SC analysis will be reviewed, including charge flow analysis and general topology comparison. Next, a novel approach to the optimization of hybrid SC converters will be introduced, which allows designers to minimize the volume of their converter while operating both at-resonance and above-resonance. Motivation for operating above resonance will be discussed and experimental hardware results will be used to help motivate the described operations. Throughout the tutorial example designs will be utilized to showcase the utility of the presented methodology, for a wide range of applications including: space applications and data centers. These examples will also showcase some of the practical implementation challenges and proposed solutions for high-performance design. Finally, general figures of merit and key takeaways will be summarized for designers’ consideration.
