Prototipo experimental de sistema híbrido basado en pila de combustiblediseño, modelado, implementación y testeo

Abstract

In this thesis is done the design, development, construction and testing of an experimental prototype of a hybrid system consisting of a fuel cell and a battery bank. The topology based on which has been designed and built all the power electronics for the connection scheme for feeding an isolated load. To this has been necessary to analyze the basis of the types of fuel cells exist, the various applications and commercial availability. As for a practical experimentation, has obtained a state model suitable for control of a system composed of a fuel cell and a DC/DC step-up converter topology. When interconnecting the two power sources (fuel cell and battery bank), according to the topology chosen, it was necessary to establish a voltage control mechanism (to set the voltage at each point because fuel cell power supply is not regulated) and a current control mechanism, because if there�s more than one source, we can decide the power rate to supply by the fuel cell. The built system can be parallelized to achieve high power concerns.
