    Since you have a RMS-DC converter, I suspect you already know the output current via this dc reading. If this is true, all it takes is a little proportional control to correct the output in relation to the input.

    The PWM will be proportional to the error in the actual output.

    If you need to measure current, use an Allegro Hall-effect sensor. Isolated, accurate, high-output.

    Yes, you are right in assuming that I have detected this current draw correctly. So, I guess I'll need to build a lookup table with the PWM percentages in it.

    Thanks again Jerson!
