Hello,

we wish to do a current mode, Active Clamp Flyback converter for Vin = 90-265VAC, and Vout = +/-50V and 2.6 Amps per rail.

Do you know what might be any disadvantages of this converter for our application?

Also, i am estimating that the Active Clamp Flyback is simply about preventing the leakage spike from killing the main FET?
-Also, there is an advantage of zero voltage switch-on

...that to me, seems to be the lot.


-It seems to do this by simply switching a low-side capacitor from drain to source after FET switch off......then letting the leakage and magnetizing inductance resonate with this clamp capacitor.

Hopwever, all the application notes that i am finding are 30-40 pages long, and still dont seem to have finished describing the technique after all that....
-does any reader know of a concise article on the current mode active clamp flyback?
