Default DC Dc converter

Morning All!
I have Mazda 6 2.2d skyactive 2018. A month ago pop up charging system malfunction. In the service change new alternator+ belt. (Alternator was faulty). Buy used from ebay dc dc converter. 3 weeks drive fine, and pop up same error. Change battery (was original battery 72 ah. which still was good condition) to 95 ah. After 20 minutes drive pop up again same error. Electrician check, brand new battery not charging up.... Computer shows dc dc converter problem. Buy another dc dc converter from ebay. Drive 2 miles and pop up again charging system malfunction. Take back to electrician, the difference is now battery is charging, alternator charging, but error still there. Computer shows dc dc converter. I don`t have capasitor and i-eloop.
