To　improve　the　current　rating　of　a　high-frequency　inverter,　multiple　phases　can　be　paralleled.　Passive　paralleling　is　normally　adopted　due　to　its　simplicity　and　effectiveness　to　balance　the　phase　currents.　In　this　paper,　a　novel　passive　current　balancing　method　is　proposed　to　introduce　an　external　LC　resonant　network　between　both　adjacent　phases.　In　this　way,　only　a　small　inductance　is　needed　to　obtain　a　very　large　equivalent　impedance　to　suppress　unbalanced　currents,　and　the　space　inductor　structure　is　easy　to　expand　to　multi-phase.　The　inductor-capacitor-capacitor　series　(LCC-S)　compensated　wireless　power　transfer　(WPT)　system　for　electric　vehicles　is　adopted　as　the　application　scenario.　An　experimental　prototype　is　built　to　verify　the　effectiveness　of　the　proposed　current　sharing　method.　©　2023　IEEE.
