In
SCR converters, or AC controllers, a high rate-of-rise
in anode-to-cathode voltage, or dV/dt, occurs
when a SCR ceases conduction, or when another
SCR in the circuit is gated into conduction. High
peak voltage is produced when an inductive circuit
connected to the SCR is interrupted. The peak
and rate-of-rise (dv/DT) of the SCR voltage must
be limited to avoid erratic circuit operation
and device damage. Connected anode to cathode,
the snubber circuit resistor/capacitor limits
dv/DT and the metal-oxide-varistor (MOV) limits
peak voltage.

TSB-1
One-Circuit
Transient Snubber
The
TSB-1 snubber board is used for one dual
SCR module, such as a single-phase AC controller.
The TSB-1 may also be used in multi-module
applications (one per module) where space
is limited.

TSB-2
Two-Circuit
Transient Snubber
The
TSB-2 snubber board would be used for two
dual SCR modules such as might be found
in a single-phase DC bridge application.

TSTB120-1
Twelve-Circuit
Snubber/Transducer
The
TSTB120-1 snubber board has voltage and
current transducer circuits that can be
input into a microprocessor for voltage
and current control in a 12-pulse bridge
rectifier application.
Typical uses would be in battery charging
applications where voltage and current are
constantly monitored.

TSB-12
Twelve-Circuit
Transient Snubber
The
TSB-12 snubber board is used typically in
12-pulse, 12 SCR DC bridge rectifiers. Another
application would be in a single-phase,
8 SCR paralleled SCRs, DC bridge rectifier.
