I am having a difficult time getting this circuit running properly. I’m not sure exactly what could be causing this, although I want to have a 400 VDC input and an output range from 20-150 VDC with a maximum of 10A. This is based off the phase\_shift\_dcdc\_converter\_with\_integrated\_magnetics file that is provided from PLECS

Hi Gianni, your question isn’t exactly clear. You are welcome to post a model describing your issue in more detail. If you re-designed the circuit, then you’ll likely have to redesign the controller as well.

As this issue appears to be related to the specific design and control of this converter, and not any particular issue/question related to PLECS, you may be better off discussing this with your colleagues.
