In this paper, according to power sharing algorithm and types (2 Con & 2 Inv, 2 Con & 1 Inv, 1 Con & 1 Inv) of photovoltaic (PV) and fuel cell (FC) hybrid generation system, control algorithms of converter and inverter are presented. Almost algorithms of PV and FC hybrid generation system are performed and verified to use by technology for commercialization. Moreover, a comparative study...
In this paper, based on the authors' previous work, a comparative analysis of input current ripple of IBC for FCEV is carried out. With the help of the detailed analysis of input current ripple, the operational characteristics will be discussed and optimal inductor size of IBC will be calculated and compared according to CCM and DCM. The theoretical analysis will be carried out and the informative...
In this paper, the characteristics of Mega-Fluxreg, JNEX-Corereg, amorphous and ferrite cores are compared for the inductor of buck-boost converter for Hybrid Electric Vehicles (HEVs). The core losses are analyzed at the condition of 10 kHz sine wave excitations. Permeability fluctuations vs. temperature and magnetizing force will be analyzed and discussed. Under the specifications of buck-boost converter...
In this paper, a new active clamping current-fed half-bridge converter is proposed, which is suitable for fuel cell power generation systems. The proposed converter is superior to conventional dc-dc converters in terms of efficiency and component utilization. The overall efficiency is estimated to be 94% at full load.
In this paper, design methodology for interleaved converters is studied in order to design high efficiency and high performance converters for fuel cell applications. Input current ripple, output voltage ripple, losses and capacity of electrical components are mainly compared with the conventional boost converters. Theoretical analysis has been performed and informative simulation and experimental...
