Power Converter Topologies for Fuel Cell- Based Hybrid Power Systems

Abstract

Power electronics is one of the key factors enabling sustainable energy technologies. Various power
circuits have recently been investigated in an attempt to explore reliable, highly efficient, high power density, and lowcost power processing systems for alternative energy generation. This paper presented the different types of power
converters suitable for use in fuel cell and battery hybrid power source for electric vehicle application. Various types
of hybrid power system configurations and associated control methods are explored. The converter topologies reported
in the literature can be broadly classified into unidirectional and bidirectional converters. For interfacing storage
devices bidirectional converters are needed, whereas for interfacing primary source fuel cell, unidirectional converter
topologies should be investigated. The feasibility of proposed converter for hybrid source has been simulated using
MATLAB.
