    Vs=170
    N1/N2=10
    N1/N3=1
    Lm=340uH
    Lx=20uH
    R=10ohms
    D=0.3
    f=500kHz
    determine the output voltage ripple

    is my work correct?

    here is another similar problem

    [​IMG]
    Vs=125V
    Vo=50V
    R=25ohms
    f=250kHz
    D=0.3

    determine turns ratio N1/N2

    how about this one, does this work appear to be correct?
