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. Why are TRIACs preferred in household electronics?
TRIACs are compact, cost-effective, and capable of handling bidirectional current, making them ideal for small, lightweight, and reliable household devices.
-
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.
