In this article, a family of interleaved high-step-down dc-dc converters is proposed integrating the valley-fill switched capacitor structure and a double-series capacitor Buck converter. This integration generates three converters, which will be extensively explored herein via theoretical and experimental analysis. A complete theoretical analysis of the structures is presented in order to mathematically explain the physical operation of the proposed topologies. A design procedure is presented for the following specifications: 300 V/12 V input to output voltage, 100 W of power and a switching frequency of 100 kHz, and the results obtained are compared to state-of-the-art dc-dc converters that enable similar high-step-down operation.
