Contraposing　the　problem　of　switching　loss　and　dynamic　response　of　boost　converter,　a　self-cascaded　boost　(SCB)　converter　based　on　phase-shifted　Full-Bridge　(PSFB)　is　proposed.　The　topology　is　realized　by　connecting　the　PSFB　converter　output　in　series　with　its　input.　The　zero-voltage-switching　(ZVS)　is　used　to　reduce　switching　losses.　By　analyzing　the　small　signal　model,　the　perfect　dynamic　response　of　the　SCB　converter　is　illustrated.　Matlab/Simulink　software　is　used　and　a　prototype　circuit　is　built.　According　to　simulation　and　experimental　waveform　data,　the　effectiveness　of　the　proposed　topology　is　verified.　©　2017　IEEE.
