-
1. 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.
-
2. 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.
-
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.
