Abstract

Fuel cells are considered strong candidates for future source of power generation. One of the main challenges in the use of this technology has been the design of dc-dc converter that provides regulated output voltage which is also 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 with no requirements for expensive components, the overall system cost has been reduced. Experimental and theoretical results are included to validate the claims
