  • Interleaved LLC power converters and method of manufacture thereof
    Patent number: 8564976
    Abstract: A system is provided having a first LLC power converter and a second LLC power converter. The first LLC power converter comprises a first LLC voltage source. The second LLC power converter also comprises a second LLC voltage source. The first LLC power converter also comprises a first resonant inductor, a first magnetic inductor, and a first resonant capacitor coupled to the first voltage source of the first LLC power converter. The second LLC power converter comprises a second resonant inductor, a second magnetic inductor, and a second resonant capacitor coupled to the second voltage source of the second LLC power converter. The first LLC power converter and the second LLC power converter are both magnetically couplable to a common load. A resonance of the first LLC power converter substantially matches a resonance of the second LLC power converter.
