    Full-bridge at +\- 50V 4Ohm will result in 25A load current 100\4=25
    we get for EI33 22uH , 25A , 5mm gap , 21turn
    Copper the twice
    So is not meaningful to apply it in a half-bridge.

    Dimonis 1mm gaps will get core hot quickly, and what about coil size? proper coil size i needed to deliver enough current through it and decrease core being hot and stress too. This thing need to be experiment in real life will tell u everything

    At 12Amps no , at more than 15 - yes

    Don't agree , if normally calculated , the is no need to experiment in real life

    Yo Stewin, any update of ur amp? My ucd now current hunger and when do parallel mosfet need more capacitor banks or the power supply will clips amd drop hard. Im now Working on short circuit protection OCP and i`ll make proper test with 60va 24 0 24 vac first after success i`ll test with smps at high current.
