    how to design a low input, high output forward converter?
    say: 50V input, 100v output

    I have tried this circuit, use LTspice simulation

    whatever I change the ratio of primary winding and secondary winding, the output can only achieve 50v, just as the input(can't be 2 times over input).

    sorry, I am just the newbie of learning power electronics.
    Hope anyone could help,give some suggestion. Thankyou.

    Keep in mind that this is a power converter. Pin=Pout-circiut losses. You have a 100A load at 50V or a 5kw load. This means your input has to rated better than 5kw.
