| Abstract |
The Fuel Cells (FC) output power is usually
generated at low voltage. The output DC voltage is not
constant and it depends on the operation conditions.
Furthermore, FC have dynamic responses that are slower
than the transient responses which are typically requested by
the loads; hence, in many applications, the FC generators
must be interfaced with other energy/power sources. For these
reasons, the FC stack output power and/or the
batteries/supercapacitors input/output power, must be usually
conditioned by means of an electronic power converter. The
main purpose of the paper is to present the issues related to
the conditioning of FC power output; in particular,
considering the specific requirements of the interface
electronic converters in the two most important applications:
mini/micro distributed generation (or cogeneration) and the
transportation systems. The paper mainly discusses the most
important circuit topologies of the DC/DC converters
dedicated to the FC power conditioning, in particular
considering the Proton Exchange Membrane FC technology. |
