Abstract:Incorporating switched-capacitor structures into isolated dc-dc converters is a promising approach to alleviate the limitations of topologies fully based on the use of high step-down transformers. In this paper, the combination of a forward converter with a series-capacitor structure is proposed for applications that require a very high step-down conversion ratio, low output voltage ripple, high output current and isolation. The result of the combination only adds one series-capacitor, one inductor, one switch… Show more
