UD1.3b: Steve Ward's Universal DRSSTC Driver schematic and board

Universal DRSSTC Driver · 2008 · revised Nov 2008 · PCB re-laid Feb 2009 · frozen as 1.3b 25 Jun 2009

Published with schematic, board files and a parts list. 24 V gate drive through a gate-drive transformer, primary-current feedback, and over-current detection with a fibre-optic option, all from ordinary logic parts so anyone could reproduce it. The photograph is the board mounted on a CM300 brick. Every later driver on this tree points back to this one.
