    Hi, I am working on a project with a galvanic isolated boost converter built by a full bridge, a transformer and a rectifier.
    I have added a measurent picture with the control signals and below the current waveform on primary side.
    My question is, why does the current not be like a triangle as it is normal for inductance due to I = 1/L * ∫ V dt ?

    Does anybody have got some reports about such circuits where current form is explained.

    There is also a lot of ringing on the current waveform, where could it come from?

    You already have a thread on this, why don´t you post a schematic there and close this one?
