1. What is a TRIAC, and how does it differ from an SCR?
A TRIAC is a bidirectional device that can control AC power, effectively working as two SCRs in parallel but in opposite directions. Unlike an SCR, which only conducts in one direction, a TRIAC operates in both directions, making it ideal for AC applications.
-
2. 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.
-
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.
