    Hi, i need help for the qustion below.
    The input Voltage to the Buck-Boost Chooper is 14V. The Duty circle is given 0.6, Frequency switching is 25Khz. Inductance = 180micro H , Capacitor = 220 micro F.
    The average load current Io= 1.5A. Determine the following task

    i) Average Vout . my.ans = 21V
    ii)The Output voltage ripple (p-p), my.ans = 0.1626V (p-p)
    iii)The Inductor current (p-p) , my.ans = 3.74A (p-p)
    iv)The peak current of the transistor Ip my.ans = 2.2497A(peak)

    Tell me if my answer are wrong, pls provide the solution as well ! TQ
