Rc Snubber Circuit Design For Relay Contacts. The moment the contacts open current will flow to the inductive load through the snubber. This arrangement is commonly referred to as a snubber circuit and they are used extensively in all sorts of different designs.
In addition the number of switching cycles can be. The rc snubber in parallel with a diode or tvs transient voltage suppressor in the above schematic very effectively clamps voltage spikes from inductive ac or dc loads. The moment the contacts open current will flow to the inductive load through the snubber.
One more thought is that an rc snubber circuit can be utilized in combination with a bidirectional tvs diode of mov.
An rc snubber can be a highly efficient circuitry in limiting the initial voltage across the opening relay contacts while the tvs or mov may be a more efficient alternative for restricting peak surge voltages. Cr type snubber this type applies to both dc and ac circuits. However the load impedance has to be lower than the rc circuit impedance when utilizing the relay for supplying the ac voltage. This arrangement is commonly referred to as a snubber circuit and they are used extensively in all sorts of different designs.
