Low-cost quasi-resonant dc-dc converter for fuel cells with enhanced efficiency

Fuel cells are considered strong contenders for future energy generation. One of the core challenges in the use of this technology has been design of dc-dc converter that provides good regulation of output voltage and is cost-efficient. This paper presents a converter topology that enhances efficiency of the system by reducing switching losses at higher frequencies by implementing a ZVS scheme. Owing to a simple control strategy and no requirements for expensive components, overall cost of the system has been reduced. Experimental and theoretical results are included to validate our claims.
