Is there any implication on not using a snubber network on a TRIAC circuit? Note the gate of the TRIAC is triggered by an opto-isolated TRIAC with zero crossing capability.
Better add a snubber!But if I am using an inductive load and I did not add a snubber hope the circuit will work?
For the capacitors I'd suggest to use X- or Y-types; there are also specialized snubber types available, e.g. Snubber MKP = SNMP or Snubber FKP = SNFP types from comp. WIMA.What type of capacitors should be used for snubbering? The current demand of my load is 10Amps, help me with the values of resistor and capacitor that should be used and If possible please attach pictures.
If you can't analyze and calculate it by a simulation, I'd suggest a rather crude estimation method. Let's take this current spike for the repeating current spike through the snubber resistor (the image is the upper part of Fig. 6 of ST's application note AN437 linked to by Tahmid above).... is there any relationship between the power handling capacity of a resistor used for snubber and the transient to be suppressed?
Don't know why. Perhaps somebody can explain it.Note: For inductive load with rms current higher than 4 A, Snubberless TRIACs are recommended.
