    Hello all,

    I want to know that how I can calculate the value of X-capacitor in order to build an EMI Differential Mode Filter.

    Kindly see the attached circuit of Isolated Full Bridge Boost Converter that I have. Inductor current is shown and just before an inductor there is a differential mode filter and I want to calculate the value of X-capacitor.

    I have determined the cutoff frequency of filter as 90KHz.

    Your help in this regard will be highly appreciated. Please help me out.
