Reverse Polarized RC Snubber Circuit
Reverse polarized snubber circuit can be
used to limit the reverse
dv/dt
. R1
will limit the discharge
current of the capacitor.

An un-polarized snubber circuit
An un-polarized snubber circuit is used when a pair of switching devices is used in anti-parallel. For
determining the resistor and capacitor values a simple design technique can be used. For this an optimum
design is needed. Hence a complex procedure will be used. These can be used to protect and thyristors.
