Abstract:
1. A system including a first inductor-inductor-capacitor (“LLC”) power converter and a second LLC power converter, comprising: a first LLC voltage source of said first LLC power converter; a second LLC voltage source of said second LLC power converter; a first resonant inductor, a first magnetic inductor, and a first resonant capacitor of said first LLC power converter coupled to said first LLC voltage source; a second resonant inductor, a second magnetic inductor, and a second resonant capacitor of said second LLC power converter coupled to said second LLC voltage source, wherein said second resonant inductor and said first resonant inductor are integral on a common core, galvanically isolated from each other and have matched inductances, wherein said common core includes a bar-shaped core portion and air gaps between whereon said first resonant inductor is positioned and said second resonant inductor is positioned on said common core; wherein said first LLC power converter and said second LLC power converter are interleaved and both magnetically coupleable to a common load.
