Can PI Expert 9 Help to design non-isolated CC supplies?

2 posts / 0 new



I want to design a dimmable CC driver non-isolated output for a 120VAC (nom) LED light engine. No matter what parameters I choose, I continue to get only isolated magnetically coupled (xformer) designs.


Am I missing something?





Please use PIXLS Designer 9 instead to help you design non-isolated LED driver based on buck or tapped-buck topology.


You can find this program inside PI Expert Suite 9 folder. When you use PIXLS Designer however, it won't generate a complete schematic. It does provide calculation for the inductor to be used, voltage and current parameters required in selecting power components.


To help you complete your design, please find from the database of DERs and RDs and use them as a guide.You can also use LED Design Selector to help you faster.
