Flying Capacitor Optimization Design for a Novel Hybrid Switched-Capacitor Converter

This paper presents a flying capacitor optimization analysis for a novel hybrid switched-capacitor (HSC) converter. This kind of DC-DC converter is a good candidate of high efficiency and high power density power supply for data centers. By utilizing this analyzing method, the selection value of flying capacitors can be optimized and soft charging operation of this novel HSC architecture will be improved. The converter can reduce the device stress, improve the power density and efficiency. The simulation models with single load and multiple loads are established respectively to verify the effectiveness of the proposed flying capacitor optimization analysis.
