1. Why do TRIACs require a DIAC for triggering?
DIACs improve the symmetry of TRIAC firing by ensuring consistent triggering voltages in both directions. This reduces harmonic distortion in AC circuits, enhancing performance.
-
2. What are the limitations of TRIACs?
TRIACs are less efficient for high-power or complex control systems due to asymmetric triggering and potential noise issues. They are more suited to low-to-medium power applications.
-
3. What precautions should be taken when using TRIACs with inductive loads?
Inductive loads can cause dv/dt turn-on issues. Adding a snubber circuit or using a zero-crossing detection mechanism can prevent premature triggering.
-
4. What are the key parameters to consider when selecting a TRIAC?
Important factors include voltage and current ratings, dv/dt capability, gate sensitivity, and application-specific requirements like power dissipation and thermal management.
