LinkSwitchTN - 3 Phase Supply without Neutral

2 posts / 0 new

I've been searching for and reviewing 3 phase application notes/design examples using the LinkSwitchTN IC and have found two or three however they all show making use of a Neutral. I believe having Neutral is not required but wanted to confirm this. My plan is to fully rectify the 3 hot legs and provide +/- signals to my existing supply design. The supply is a simple on-line supply and hot legs are max 250VAC. Is there any issue with this?

Hi, can you share your design for verification?
