Continuous input-current buck-boost DC-DC converter for PEM fuel cell applications
MetadataShow full item record
This paper proposes a buck-boost converter topology with continuous input-current capability for proton exchange fuel cells (PEMFC) systems. The continuous input-current feature of the converter contributes to maintain the PEMFC life-time, which is in sharp contrast with traditional buck-boost converters whose input currents damage the PEMFC and reduce the efficiency. Moreover, this converter offers the main advantages found in traditional topologies, such as the Cuk or the SEPIC converters, using a reduced number of electronic components. In particular, the topology features buck-boost conversion range capability, low input-current ripple, and a simple low-cost structure. A detailed analysis that encompasses steady state analysis, dynamic modelling, stability analysis, control and experimental results are provided. © 2017 Hydrogen Energy Publications LLC
