A Micro Fuel Cell Power Supply Module for Low Power Portable Applications
نویسندگان
چکیده
This paper presents a power supply module targeted for low-power applications in the sub-mW range incorporating a passive μDMFC fuel cell (μFC) acting as energy source and a customized boost converter for the energy conversion. The low power budget of such energy sources mandates the adoption of efficient circuit solutions, hence the design of the boost converter is challenging. To maximize the lifetime of the micro fuel cell, the module has been designed to keep constant the μFC operating point and it has been optimized to work with μFC providing a voltage in the range 280mV-320mV, reaching a maximum efficiency higher than 65% with an output power of 350 μW.
