i'm doing a project on design a forward converter with these specification:

minimum input voltage = 100Vac
output voltage = 20V
output power = 100W
switching frequency = 100kHz

anyone can give me a proper calculation on the project?
 

I am no expert but, as a junior power electronics person I can say that:

The shunt capacitor depends on the ripple allowed but probably around 470uF or so will probably give a smooth output. The diodes and the power MOSFET should be fast switching.

But,

Designing forward, flyback or similar converters involves designing the transformer in the first place. I do not know if some exact values could be given without completing that phase first.
Considering a fine DC, you should find a suitable turns ratio then selecting an appropriate Lm value to enable a power transfer you should determine the number of turns.
