The ΔV-Method: An Intuitive Method for Analyzing Soft-Charging Capabilities of Hybrid Switched-Capacitor DC-DC Converters

This paper presents an inspection method for analyzing the soft-charging capabilities of switched-capacitor converters (SCC). The method utilizes a multi-step visual approach to derive the voltage changes (ΔV) across each flying capacitor, leading to an intuitive way of understanding the behavior of hybrid-SCC topologies on circuit level. The method is presented by examples and is used to obtain capacitance ratios and split-phase timings for Hybrid Dickson topologies.
