Enerpro - TSB-6 Snubber Circuit Protection

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. Enerpro Inc have designed The TSB-6 snubber board for use typically in 3-phase, 6 SCR, single-phase 4 SCR DC bridge applications.
