Other Parts Discussed in Thread: UCD3138, UCD7138
It seems that the "reply" to Brian's response was not put in correctly.
Here is the related question:

Biran
Thnx much for the prompt reply.
Now it gets a bit interesting & perhaps challenging.
Here is why.
#1 So we will use the control card until we have our own sch integrated with the rest of the package. We see a path forward with mathworks as they have deep levels of support for F28379D. The initial control will be through simulink modeled PID but down the road, we have to add a Fuzzy Logic Controller in its place as the PID won't satisfy all the specs. So we have to keep enough computing/memory power available. Albeit, ours will be a simple FLC. Only voltage mode will suffice.
#2 We were using UCD3138 based HB-LLC for a 380v to 5/80 amp module. But now thinking, would it be possible to have the Delfino run both?
We have a bit of a real estate issue on the PCB in a tight enclosure( with no other thermal mgmnt than the base plate). So if we do not have to use the whole inslata with UCD3138 control card, it will be a great benefit. Note in passing that in order to squeeze all the LLC stuff in, we use GAN all over including the sync rectifiers (EPC2024) using UCD7138. Delfino has a FB-LLC design guide, FW etc... a matter of scaling the output & other parameters.
#3 Even though Interleaved FB-LLC will need another set of LLC power stage, somehow, it is not a problem! Our 2x40 amp pkg is really small. It entirely entails from having very high efficiency.
So how will this path look like? Having 2 independent converters controlled by one Delfino with 2 distinctly different control scheme? Feedbacks for each, of course, are isolated. Drivers are isolated( & compact - no xmfrs) so grounding issues are well managed.
Any comments will be highly appreciated.
