Mass commercialization of fuel cells (FC) and its usage in transportation requires that the FC technology to be competitive with regard to performance and cost, while meeting efficiency and emissions targets. Therefore, fuel cell output current ripple that may shorten FC lifespan, worsen FC efficiency and reduce the FC output capacity need to be addressed. In this paper, an improved multi-device interleaved boost converter (MDIBC) with novel multiplex controller topology is designed to further reduce the input current and output voltage ripples, without increasing the number of MDIBC switching devices. The Matlab/Simulink behaviour model of the improved MDIBC with novel multiplex controller and conventional MDIBC circuit are developed in the simulation studies. The proposed improved MDIBC design is then compared with the conventional MDIBC and its performance is verified.

Renewable energy is derived from natural resources and most commonly used renewable energy system is photovoltaic cells. DC-DC boost converter serves many purposes and usually required in many applications which has a low output voltage such as batteries, photo-voltaic cell. In this paper interleaved boost converter (IBC) topology is discussed for solar energy generation. IBC have better performance characteristics compared to a conventional boost converter due to increased efficiency. DC-DC IBC have been considered and analyzed by input current ripple and output current ripple and output voltage ripple. The waveforms of voltage and current ripples and the output voltage are obtained by using MATLAB/SIMULINK are presented. The design of inductor, capacitor and analysis of ripples has been presented.

Interleaved Boost Converter

This paper investigates the state space averaging of a four-phase Interleaved Boost Converter (IBC) powered by fuel cells. The state space averaging technique is a method to model the converter as time independent which is defined by a set of differential equations which will be useful for designing the controllers [18]. In this paper, mathematical models developed using state space averaging technique are presented for the proposed IBC. The power loss calculations are also computed. Simulation of IBC with fuel cell as the source is carried out in MATLAB and the results are presented and discussed.

This paper deals with analysis of the four phase interleaved DC-DC converter for higher power application. The interleaved topology is widely used due to  its advantage as lower input current ripple which means volume reduction of the input capacitor. The current ripple equation of an input current for the boost operation mode and the ripple current in the individual phase of the interleaved converter using uncoupled inductor are shown. The theoretical equations are supplemented by the simulation results using the Spice simulator and by measurement on the interleaved converter.

Sustainable Power

Fuel cell is one of the promising renewable and sustainable power sources because of its high power density and very low emission. In order to design a highly efficient fuel cell power system, a suitable DC-DC converter is required. In this paper, a four-phase directly coupled Interleaved Boost Converter (IBC) for fuel cell is proposed. A four-phase structure with interleaved control is proposed to reduce the input current ripples, the output voltage ripples, and the size of passive components with high efficiency compared with the other topologies. Mathematical analysis of overall current ripple, design of inductance and other components is investigated. Simulation study of the proposed converter interfaced with fuel cells is carried out using MATLAB. A prototype is built using MOSFET to validate the simulation results.
