Digital Control of an Isolated Active Hybrid Fuel Cell/Li-Ion Battery Power Supply

In this paper researchers present a method of preserving high energy density during periods of higher peak power in electronic equipment. An implementation of hybrid fuel cells/battery systems is presented with a dc/dc power converter that controls the power flow between the fuel cell and the battery system. Researchers both design and implement a power electronic interface system to be used in a hybrid solid-oxide fuel cell (SOFC)/Lithium-ion battery power supply. Implementing this active isolated hybrid power supply has applications for modern portable electronic devices as well as in vehicular systems. While a dc/dc buck converter can be used for control in this system, an isolated dc/dc converter must be used in order to better isolate the fuel cells from the load. Researchers have also introduced a new digital control technique for the system and have found, using experimentation and simulation, that the system has a very fast dynamic response in the event of a load disturbance.
