Abstract

Abstract: This paper investigates the modeling approach based on the Matlab SimPowerSystems Toolbox (SPS) of a fuel cell electric vehicle (FCEV). The objective of this approach is to increase the accurate modeling of the power source, the power converter and the load to evaluate the full system performances since the simulation step. In this study, a supercapacitor (SC) is associated as an auxiliary device with the FC to ensure the power reversibility in the drive train. The FC and the SC are connected to the dc bus throughout an interleaved boost converter (IBC) and an interleaved buck-boost converter (IBBC) respectively. The control of the proposed system is designed using the discrete proportional integral (PI) controllers and the digital width pulse modulation (DPWM). The proposed controller improves the dynamic performance of the IBC converters by achieving a robust bus voltage and inputs currents against load disturbances. The converter is designed through simulation using SPS and the results are discussed. Highlights: A fuel cell and supercapacitor is proposed for electric vehicle applications. A simulation approach to increase the accurate modeling is presented. A digital controller and a digital pulse width modulation are used. Interleaved converters are proposed for the control of power flow in the system. The proposed system is developed using Matlab Sim-Power-Systems toolbox.
