With　low-voltage　and　high-current,　it　is　often　to　run　the　converter　in　parallel　to　improve　its　efficiency　and　reliability　in　high-power　applications.　Since　the　gain　of　the　LLC　resonant　converter　is　very　sensitive　to　component　parameters,　current　sharing　problem　caused　by　inconsistency　of　component　parameters　between　each　phase　is　more　prominent　when　working　in　parallel.　Based　on　the　principle　of　reducing　the　sharing　current　error　source,　there　was　a　parallel　LLC　resonant　converter　with　automatic　current　sharing　characteristics　presented　in　this　paper.　With　the　resonant　capacitors　common　using　and　the　resonant　inductors　coupling,　there　was　a　better　current　sharing　characteristics　can　be　automatically　achieved　without　any　other　additional　components　or　control　strategies.　In　this　paper,　the　time　domain　models　of　the　converter　were　established　and　the　characteristics　of　the　current　sharing　error　were　analyzed　when　the　resonant　inductances,　resonant　capacitors　and　excitation　inductances　appeared　asymmetry.　Compared　with　the　traditional　parallel　LLC　resonant　converter,　the　results　of　simulation　and　experiment　showed　that　there　were　better　current　sharing　characteristics　achieved　in　the　proposed　parallel　LLC　resonant　converter　under　the　same　condition,　which　was　in　high　agreement　with　the　theory　deduction.　©　2018　Chin.　Soc.　for　Elec.　Eng.
