Abstract：

A　novel　inductor-capacitor-transformer　(L-C-T)　has　been　proposed　to　integrate　the　passive　components　into　an　integrated　magnetic　component.　The　phase-shift　full-bridge　(PSFB)　zero-voltage　switching　(ZVS)　converter　with　a　novel　L-C-T　has　high-power　density　performance,　which　is　used　in　electromagnetic　exploration.　The　structure　of　the　novel　L-C-T　is　very　complicated,　and　the　lumped　parameter　of　the　L-C-T　is　very　difficult　to　determine.　Based　on　the　dual　method　of　the　magnetic　circuit,　the　electromagnetic　energy　method　and　the　six-lumped　capacitance　method,　a　lumped　parameter　model　suitable　for　the　novel　L-C-T　is　proposed.　Moreover,　the　experiments　and　finite　element　analysis　(FEA)　are　used　to　verify　the　accuracy　of　the　lumped　parameter　model,　and　a　40　kW　prototype　of　the　PSFB　ZVS　converter　with　a　novel　L-C-T　is　designed　and　tested.　©　2019　Institution　of　Engineering　and　Technology.　All　rights　reserved.
