Proposal of a switch-mode power supply by the association of an interleaved boost-flyback converter and an interleaved forward topology

This work presents the analysis of a switch-mode power supply operating at high switching frequency with high efficiency. An almost unity input power factor is obtained when an interleaved boost-flyback converter associated with a nondissipative snubber is used as a preregulator stage. An interleaved forward converter is used as DC-DC stage, as the combination of both topologies results in the proposed SMPS. Theoretical background on each one of the converters is presented, and analytical results on the proposal are discussed in order to validate the proposal.
