HF transformer losses less with reduced magnetization path

    Hi all,

    I have two Metglas C cores forming a high frequency transformer O
    core. I found that wrapping primary and secondary windings on the
    same bobbin as opposed to wrapping them on separate bobbins on
    opposite sides of the core has a profound improvement in transformer
    core efficiencies. I am aware that doing so would reduce the
    leakage inductance significantly, but that shouldn't affect core
    hysteresis efficiencies (up to 10% more efficient) I would think
    since
    I'm recycling flyback currents anyway. Perhaps covering half the
    transformer with windings instead of most of it reduces core eddy
    currents, but as these cores are laminated composites I believe the
    eddy currents are low as it is. Either way, with a reduced
    magnetization path the coupling is better. I just don't quite
    understand what core loss mechanism is subdued in doing so. Any
    ideas?


    Thank you,


    JT
