چکیده
When the fuel cell (FC) is being activated before used in industrial applications, a power conditioner needed to interface FC with load. Due low current ripples, high output power, and simple structure, multi-phase interleaved non-isolated DC-DC converter most suitable for conditioner. This paper proposed, analyzed designed four-phase buck-boost changed load connection (CLC-FIBC) activation characteristics as wide input current, ripples. The operating principle mathematical model of CLC-FIBC were firstly analyzed, derived presented, then equations transistor voltage stress inductor ripple are respectively. Besides, this was compared several converters prove superiority. simulation experimental prototype built validate theoretical analysis after presenting some design considerations. Simulation results show that has both step up/down function, range,

متن کاملA Novel Interleaved DC-DC Converter with Reduced Loss for Fuel Cell Vehicle Application
In this paper a novel four-leg interleaved DC-DC boost converter is proposed which is well suitable for fuel cell vehicles (FCV) application. The voltage stress of two switches of this converter is half of the conventional interleaved converters. Therefore, smaller and cheaper switches can be utilized. Also "on" state duration of the two of four switches are reduced in comparison with...
