Snubber design is an art. They can be used to tailor load lines to
minimize device dissipation and/or to stay inside of safe operating
limitations.
Back in the early '80's I did an off-line 200W switcher for GenRad
using HV bipolar devices (MJE-something-or-other, TO-220,
half-H-bridge).
I used a current probe and a voltage probe to get V-I load line plots,
and got switching very nearly right along the axes (*)
Ran so cool I took off the heat-sinks.
Then I wondered how "cool"?
Without thinking I grabbed a flag to see... forgetting that there was
340V P-P there... instant entertainment for the technicians ;-)
