    It's just the total area under the curve during one period (that is, the time integral of the current over one period), divided by the period.

    You know the formula for the area under a trapezium?

    [tex]A = (a + b)\frac{h}{2}[/tex]

    Or in this case:

    [tex]( I_{min} + I_{max} ) \frac{t_{on}}{2}[/tex]
