摘要
BasedonthetransmissionlinecodeTLCODE,a1Dcircuitmodelforatransmissionlineimpedancetransformerwasdevelopedandthesimulationresultswerecomparedwiththoseintheliterature.Themodelwasusedtoquantifytheefficienciesofvoltage-transport,energytransportandpower-transportforatransmission-lineimpedancetransformerasfunctionsofΨ(theratiooftheoutputimpedancetotheinputimpedanceofthetransformer)andΓ(theratioofthepulsewidthtotheone-waytransittimeofthetransformer)underalargescaleofm(thecoefficientofthegeneralizedexponentialimpedanceprofile).SimulationresultssuggestthatwiththeincreaseinΓ,fromOto∞,thepowertransportefficiencyfirstincreasesandthendecreases.Themaximumpowertransportefficiencycanreach90%orevenhigherforanexponentialimpedanceprofile(m=1).Withaconsiderationofdissipativelossinthedielectricandelectrodesofthetransformer,tworepresentativedesignsofthewater-insulatedtransformerareinvestigatedforthenextgenerationofpetawatt-classz-pinchdrivers.Itisfoundthatthedissipativelossesintheelectrodesarenegligiblysmall,below0.1%,butthedissipativelossinthewaterdielectricisabout1%to4%.
