review of diode defence,6 pulse rectifier

["Tesla list" <tesla@xxxxxxxxxx>]

....100k ohms in parallel with 0.1 uF is very common when we have a 6-40 amp
DC supply to work with (BTW: my frame of reference is 50-800kW plate
supplies). The resulting losses may be unacceptable with the size of
your dc supply (1.4 amp diodes were mentioned?), however, so you may
need to increase "R" and "C".

Reverse recovery time is not really the issue as was said, we just want
to buy time when we have a fault, and things start to ring (like that
big choke!)

With that much series inductance btw, consider a 7th diode stack across
Vdc as close to the rectifier terminals as possible. -This- rectifier
could benefit from reduced turn off time.
***** are you speaking to what is otherwise know as dequing in resonance
charging or something different as in slamming the door? I assume there
should be a few more diodes in this string as it sees the full forward and
reverse voltage, I still need to call their tech support and will
adivise****
