Tapewound cores do offer higher flux densities and better tempera-ture stability, advantages which may off-set their higher is an excellent material for high frequency (20 kHz to3 MHz) inverter Power supplies.
TRANSFORMER CORE SIZE SELECTION The power handling capacity of a transformer core can be determined by its WaAc product, where Wa is the available core
