Calculating B of inductor operating in continuous conduction mode?

  1. May 18, 2013 #1
    Hello everyone,

    I am working on a coil design and have a question.

    The coil is meant to operate in continuous conduction mode, so the current waveform is a ramp waveform.

    B=V*t / N*Ae

    When calculating V*t do I use 1/2 t (since the current only increases for the first half of the ramp waveform) or do I use the full length of t?

    Flux and current are in proportion ;
    ....so just multiply current by a constant ?

    but probably I misunderstand.
