1. What are the main uses of TRIACs?
TRIACs are commonly used in phase control applications like light dimmers, motor speed controls, and heaters, as well as in domestic appliances where bidirectional AC control is needed.
-
2. 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.
-
3. How can flickering in TRIAC circuits be minimized?
Flickering can be addressed by proper circuit design, including snubber circuits to handle dv/dt issues and filtering to reduce noise and harmonics.
-
4. 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.
