“…Practical converter designs involve several considerations beyond just sizing of power transistors and passive components. These include factors such as VCR (DC gain) range, number of switches, gate driving, level shifters, capacitor charge balancing [33], [50], [62], voltage stress during the starting phase [52], feedback control [47], [48], [63], PCB routing, input capacitor [64] and EMI. While these considerations may make the low N topology an appealing choice, a final decision must take into account all relevant factors with appropriate weighting depending on the application.…”

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.

“…Most reported BFCs struggle to produce sufficient voltages to power the intended devices, and as such, many groups have increased the voltage output of their BFCs using custom [37,137,138] or commercial DC-DC voltage boosting circuits which solve this issue in a simple manner. Boosting circuits can bring low voltage sources into the range of conventional batteries, enabling powering of common electronics.…”

Recent developments in wearable and implanted devices have resulted in numerous, unprecedented capabilities that generate increasingly detailed information about a user's health or provide targeted therapy. However, options for powering such systems remain limited to conventional batteries which are large and have toxic components and as such are not suitable for close integration with the human body. This review provides an in‐depth overview of biofluid‐activated electrochemical energy devices, an emerging class of energy sources judiciously designed for biomedical applications. These unconventional energy devices are composed of biocompatible materials that harness the inherent chemistries of various biofluids to produce useable electrical energy. This article covers examples of such biofluid‐activated energy devices in the form of biofuel cells, batteries, and supercapacitors. Advances in materials, design engineering, and biotechnology that form the basis for high performance, biofluid‐activated energy devices are discussed. Innovations in hybrid manufacturing and heterogeneous integration of device components to maximize power output are also included. Finally, key challenges and future scope of this nascent field are provided.This article is protected by copyright. All rights reserved
