    LLC converter with F(sw) > upper resonant frequency

    Why does page 7 of the following say that in an LLC converter, operation with fs>fr results in hard commutation of the secondary diodes? This is not the case.

    Re: LLC converter with F(sw) > upper resonant frequency

    it's simply wrong ...

    however you can get hard commutation of the o/p diodes for Fsw > Fres if the leakage is too high ...
