This paper proposes a model to yield power from the low-power sources like microbial fuel cell (MFC). The structure of the MFC with a suitable energy storage unit is proposed and discussed in detail. The prototype of the MFC model with the charge pump (switched-capacitor) circuit is implemented and tested for an output voltage of 5V. Additionally, a novel high-step-up converter is suggested for the low-power applications. It employs a passive switched-inductor–capacitor cell (PSLC), which makes the switching of the LC network simple. This high-gain converter is derived by replacing the diode in the primary switched inductor cell with a capacitor. Compared to several topologies with similar voltage conversion ratio in the literature, the derived converter can achieve high voltage gain with the lesser component count. This study directs to propose a compact and lightweight DC–DC converter. Since the suggested topology is for low-power applications, a 5-W prototype is tested. The implemented setup is most appropriate for microbial fuel cell application, which is closely related to environmental stewardship.

用于微生物燃料电池的具有开关电容电路的可扩展 PSLC 网络高增益 DC-DC 转换器

本文提出了一种从微生物燃料电池 (MFC) 等低功率电源中发电的模型。提出并详细讨论了具有合适能量存储单元的 MFC 的结构。实现了带有电荷泵(开关电容)电路的 MFC 模型原型,并针对 5 的输出电压进行了测试V. 此外,针对低功率应用提出了一种新型的高升压转换器。它采用无源开关电感-电容单元 (PSLC),这使得 LC 网络的切换变得简单。这种高增益转换器是通过将初级开关电感单元中的二极管替换为电容器而获得的。与文献中几种具有相似电压转换比的拓扑相比,衍生转换器可以以更少的元件数量实现高电压增益。本研究旨在提出一种紧凑且重量轻的 DC-DC 转换器。由于建议的拓扑适用于低功耗应用,因此测试了 5W 原型。所实施的设置最适合与环境管理密切相关的微生物燃料电池应用。
