“…A DC/DC converter, like boost, offers higher efficiency and less component count comparated to other DC/DC converter topologies like half bridge, push pull, flyback and full bridge etc [9], which can be used to interface the FC system to the load [10]. So considering that the FC has a slow response, a secondary energy source is often desired to help maintain bus voltage during transients and start-up [11].…”

This paper presents a new control strategy to operate a Proton Exchange Membrane Fuel Cell (PEMFC) 1,2kW and Supercapacitor (SC) through a hybrid converter proposed. The Fuel Cell (FC) has a slow dynamic device by its nature; therefore it is recommended to have an additional auxiliary power such as the SC to improve system performance in all its applications. So has been made a study of the DC/DC converters as well as control strategies employed recently used to operate the FC and SC system. This paper shows an experimental validation of the system which has been simulated in Matlab-Simulink. For this two test have been proposed using different load demands of power and cut off FC power . Under disturbances from FC voltage and load voltage these tests are possible to verify that the system achieves an excellent output voltage (Vo) regulation and SC Voltage (V SC ) control.

“…Fuel cells brought other challenges to power electronics like the need for low input current ripple, in order to reduce the ripple of the stack voltage and this is why current-fed converters are usually specified as a good power electronics interface for them [7]. The study of these kinds of converters as power electronics interfaces between the fuel cell and the load is usually performed through analytical calculations to describe their operating behaviour [9] or simulations with usual DC voltage sources instead of fuel cell system models as this paper proposes [10]. The advantages of such a study are obvious.…”

Abstract. Standalone power systems for telecommunications are becoming an emergent need, due to environmental problems and their current tendency to be localized in remote places. Along with photovoltaic and wind generators, fuel cells are one of the most mature technologies to be employed in this kind of systems. As they are expensive and complex systems, it is important to simulate their behaviour to study different operating modes. This paper intends to propose a simulation of a fuel cell system with a voltage-fed full-bridge converter in the Matlab-Simulink © environment fulfilling the strict telecommunications equipment requirements.

Fuel cells are an attractive option for alternative power and of use in a variety of applications. This paper proposes a state space model for the solid oxide fuel cell (SOFC) based power system that comprises fuel cell, DC-DC buck converter, and load. In this investigation we have taken up a case study for SOFC feeding a DC load where a DC-DC buck converter acts as the interface between the load and the source. A proportional-integral (PI) controller is used in conjunction with pulse width modulation (PWM) that computes the pulse width and switches the MOSFET at the right instant so that the desired voltage is obtained. The proposed model is validated through extensive simulation using MATLAB/SIMULINK. Controller for the fuel cell power system (FCPS) is prototyped using XC3S500E development board containing a SPARTAN 3E Xilinx FPGA that simplifies the entire control circuit besides providing additional flexibility for further improvement. The results clearly indicate improved performance and validate our proposed model.
