“…Section I will delve into these cases where capacitors cannot be deemed negligible in determining the total volume. more ditacted by DCR than by the saturation current [74]. In this case, a clear linear relationship between the inductor volume and DCR, R L , can be observed for the same inductor value.…”

Hybrid switched-capacitor converters (HSCCs) have gained attention due to their promising efficiency and power density compared to traditional inductor-or capacitor-based converters. However, with the recent development of various HSCC topologies, it has become increasingly challenging to choose the most suitable one for a particular application. To address this challenge, this paper proposes a benchmarking framework that enables direct comparison of direct HSCC topologies based on various performance metrics such as passives volume and bandwidth. The proposed approach, which compares all topologies at the same efficiency and output voltage ripple, provides guidelines for topology selection and optimization, ultimately contributing to wider industrial adoption and exploration of new topologies. Downloadable open-access code is also provided to recreate presented results and expand to other topologies not discussed in the paper.INDEX TERMS DC-DC converter, hybrid converter topology, switching converters.
