This paper presents an isolated three-phase power-factor correction rectifier using a Scott autotransformer and using two single-phase single-stage (S2) isolated current rectifiers with power factor correction, based on a Full-Bridge Flyback converter. The Scott autotransformer provides a phase reduction allowing the use of two single-phase rectifiers. The proposed converter can operate as a step-down...
This paper presents an AC-AC Buck converter in which a modulation technique was applied in order to reduce losses due to dissipative snubbers. Theoretical analysis and numerical simulation were performed. A 100W prototype was built and tested. Efficiency curves show that snubber losses are minimized with the use of a simple open-loop control technique.
A high static gain DC-DC converter based on the CUK topology is presented in this paper. The proposed converter presents an input and output current source characteristic allowing the integration of this converter with a second stage with input current source characteristic. Some applications of the proposed converter are renewable power sources and grid-tie systems. The theoretical and experimental...
