Resonant Transformers

+ Two-chamber design → Built-in leakage inductance/resonant LLC tank → minimize PCB components

+ Multiple voltage levels from auxiliary windings

+ Customize ratio magnetizing inductance to parasitic capacitance → zero voltage switching + gain curve → minimal switching losses

+ Possible bidirectional power conversion (CLLC)

• Power ranges:
        o   Conventional half-bridge converter → up to 1kW
        o   Interleaved half-bridge converter → 1kW+
        o   Conventional full-bridge converter → 3.7kW to 6.5kW 
        o   Interleaved full-bridge converter → 10kW+
