I'm glad you have resolved your reliability/stability problems with THOR's
power supply.  Amazing how EMI will cause massive problems with
clocked systems (TTL or CMOS) much less a Power Electronics system,
and how something as simple as effective shielding + optoisolation can
dramatically improve system reliability.
.
I have downloaded the schematics and will review further.  Thanks!
