August 18, 20233 yr Hi im hoping to find a circuit diagram or manual showing the origin of -5V and +15V supplies for the opto's switching IGBTs in the AC conversion circuit...
August 18, 20233 yr There are a few service manuals in the files section of this forum. It MAY or may not be similar enough to the 5 kVA circuit to be able to use Maxo's schematic, first link here. Edited August 18, 20233 yr by Coulomb
