摘要

本文介绍了一种超低电压、超低功率DC/DC变换器。这种转换器从微生物燃料电池(MFC)中获取能量，以便为另一个电路(如自主无线传感器)供电。MFC作为475mV开路电压的电压发生器，具有600Ω串行内部阻抗。因此，最大输出功率约为100μW。DC/DC变换器提供2-7.5V范围内的输出电压，并与源阻抗匹配。当与MFC相关联时，转换器达到60%的峰值效率。此外，该DC/DC变换器无需外部启动辅助电源即可自操作。

Autonomous ultra-low power DC/DC converter for Microbial Fuel Cells

In this paper, an ultra-low voltage and power DC/DC converter is presented. This converter harvests energy from a Microbial Fuel Cell (MFC) in order to feed another circuit such as an autonomous wireless sensor. The MFC behaves as a voltage generator of 475mV open-circuit voltage with a 600Ω serial internal impedance. The maximum delivered power is therefore around 100μW. The DC/DC converter provides output voltage in the range 2–7.5V and performs impedance matching with source. The converter achieves when associated with the MFC, 60% peak efficiency. Furthermore, this DC/DC converter is self-operating without the need for external power source of start-up assistance.
