Flyback RCD snubber All About Circuits

WebIn case of a Flyback converter, the RCD clamp is supposed to dissipate only the energy stored in the leakage inductance. However, in case of a Forward converter it would dissipate the energy from the magnetizing inductance (and by that resetting the core). But isn't that power dissipation so much that it makes it unacceptable?
