    Abstract

    In recent years, the use of electrolyzers to produce cleanly and efficiently hydrogen fromrenewable energy sources (i.e. wind turbines, photovoltaic) has taken advantage of agrowing interest from researchers and industrial. Similarly to fuel cells, DC/DC convertersare needed to interface the DC bus with the electrolyzer. Usually, electrolyzers require alow DC voltage to produce hydrogen from water. For this reason, a DC/DC buck converter isgenerally used for this purpose. However, other DC/DC converter topologies can be useddepending on the feature of the electrolyzer and electrical grid as well. The main purposeof this paper is to present the current state-of-the-art of DC/DC converter topologies whichcan be combined with electrolyzers. The different DC/DC converter topologies arecompared in terms of output current ripple reduction, conversion ratio, energy efficiency,and power switch fault-tolerance. Besides, remarks on the state-of-the-art and remainingkey issues regarding DC/DC converters are provided.© 2017 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
