Among many converter topologies that have been proposed and developed for low voltage fuel cell applications, isolated full-bridge Buck and Boost converters appear to be the most popular. Although the Buck topology is considered to be superior in performance, particularly for being more efficient, this claim has never been proved with a `proper' comparison to the Boost topology. This paper presents...
A new simple and low cost method for paralleling multiple power stages in high-power high-gain isolated full-bridge boost converters is presented. A small current balancing transformer and serial connection of transformer secondary windings provides ideal current sharing between paralleled power stages. Effective and safe parallel operation of multiple switching stages can thus be performed. By splitting...
