    Implement PFC controller properly to AC/DC converter

    I am trying to implement a PFC controller to AC/DC converter stage, but I have some problems to get the current feedback correctly so the output is more steady state. Also, the waveform have transients in the beginning, it is possible to reduce these transients? I have connected a transistor...
