Modeling, Analysis, and Design of an Interleaved Four-Phase Current-Fed Converter With New Voltage Multiplier Topology

摘要: The objective of this paper is focused on developing an interleaved four-phase current-fed converter with new voltage multiplier topology for low-voltage distributed energy generation systems. proposed the configuration and preserving inherent advantages smaller input current ripple inductance size. Through topology, high gain can be achieved using relatively lower transformer turns ratio. Also, stresses both active switches rectifier diodes are greatly reduced so that low on-resistance adopted, reverse-recovery effect decreased naturally. dc ac small signal models derived better closed loop control, some design guidelines then given circuit implementation. Both simulation experimental results indeed verify effectiveness converter.
