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. What is the significance of the main terminals (MT1 and MT2) in TRIACs?
The MT1 and MT2 terminals are not interchangeable. Correct configuration is critical for TRIAC operation, as gate current must flow relative to MT2.
-
4. How does dv/dt affect TRIAC performance?
A high rate of voltage change (dv/dt) across the TRIAC can unintentionally trigger it. Snubber circuits are used to limit dv/dt and ensure reliable operation.
