Model based control of modified four-phase interleaved boost converter for fuel cell power source for mobile based station

Abstract : This paper proposes a modified 4-phase interleaved converter for the FC power source for mobile based station applications. The ripple and harmonic content of the FC current is one of the various phenomena influencing FC lifetime. The main objective of this research is to minimize inductor size, capacitor, current/voltage ripples, and harmonic content. The main contribution is to presents a control law for a distributed dc generation supplied by a FC generator. Classically, to control the voltage, the current, or the power in the converter, a linearized technique is often used to study the stability and to select the controller parameters of the nonlinear converter. In this paper, a nonlinear-control algorithm based on the flatness property of the system is proposed. Utilizing the flatness property, we propose simple solutions to the system performance and stabilization problems. Design controller parameters are autonomous of the operating point. To authenticate the proposed control laws, a test bench is realized in the laboratory. The control algorithm is digitally implemented by dSPACE controller DS1104. Experimental results with small-scale device (a proton exchange membrane FC (PEMFC) of 1.2 kW, 26 V) substantiate the excellent performance during load cycles.
