Overvoltage Protection Circuits
RC1
TSE snubber circuit
RC2
To avoid over voltages due to the reverse recovery
charge effect every diode/thyristor is equipped with a
parallel RC snubber which absorbs the charge/energy
and which is a damping for possible oscillations.
input snubber bridge
To absorb surge voltages of higher magnitude inrushing
from line an auxiliary rectifier is mounted in parallel to
the rectifier. This auxiliary rectifier has a storage
capacitor connected to the output which will absorb
inrushing surges. Besides this there is also a restricted
functionality as TSE.

ARC
AC side RC snubber
DRC
To absorb surge voltages of lower magnitude inrushing
from line RC snubber are placed phase to phase on the
Ac side of the rectifier
(recommended for DC currents up to 200A)
DC side RC snubber
To avoid overvoltage at the DC side of a rectifier a RC
snubber is mounted. This is helpful if there is no
capacitor as DC link close to the rectifier output
