This paper presents an efficient power management circuit (PMC) for microbial fuel cells (MFCs). The proposed PMC has been designed with off‐the‐shelf components including a charge pump, a supercapacitor, and two boost converters. Both the charge pump and one of the boost converter are directly connected to the MFC, that is, connected in parallel to the MFC. The reason for that using the charge pump can extend the variety of PMC input power, and deploying the boost converter can extract more power from the MFC. Thus, the proposed PMC can test the input power range from 11.25 μW to 1.6 mW. Also, the proposed PMC can extract 6× higher power from the MFC as compared with the charge pump alone. A wide dynamic load range from 10.89 μW to 108.9 mW can be supported by the proposed PMC. Measured results show that the interval to provide power supply to the load by the proposed PMC is 9.2× shorter than that achieved by the charge pump alone. Also, the proposed PMC enhances the end‐to‐end efficiency by range from 10× to 14.35× with varying loads. The proposed PMC achieves the end‐to‐end peak efficiency of 73.185%. The proposed PMC can achieve a low charging time, a wide dynamic load range, and a regulated output voltage compared with prior works.

基于生物质的能量收集系统的高效电源管理电路
本文提出了一种用于微生物燃料电池（MFC）的高效电源管理电路（PMC）。拟议中的PMC设计有现成的组件，包括电荷泵，超级电容器和两个升压转换器。电荷泵和升压转换器之一都直接连接到MFC，即与MFC并联。使用电荷泵可以扩展PMC输入功率的种类，而部署升压转换器可以从MFC提取更多功率。因此，建议的PMC可以测试11.25μW至1.6 mW的输入功率范围。而且，与单独的电荷泵相比，所提出的PMC可以从MFC提取6倍高的功率。提议的PMC可以支持从10.89μW到108.9 mW的宽动态负载范围。测量结果表明，所提出的PMC为负载提供电源的间隔比仅由电荷泵实现的间隔短9.2倍。此外，在负载变化的情况下，建议的PMC可以将端到端效率提高10倍至14.35倍。提议的PMC达到了73.185％的端到端峰值效率。与以前的工作相比，拟议的PMC可以实现较短的充电时间，宽的动态负载范围和稳定的输出电压。
