RM14-3C96 can handle maximum 200W at 100KHz switching frequency
Can i expect more power in case of full-bridge converter?
Forward and full bridge topology can expect two times power than flyback topology with same core and same frequency.
Copper filling factor
is the fill factor, or the wire lay, for the usable window area. or window utilisation factor normally consider .85 to .9 (.85 for small wire and .9 for thick wire)
Normally Fulbridge not required air gap but very small air gap will avoid saturation when high current
