28 Triacs | Power Electronics

The video tutorial discusses the operation and applications of thyristors and TRIACs. It explains how TRIACs can control current in both directions, making them useful in devices like lamp dimmers and home appliances. The tutorial covers the construction of TRIACs, their terminals, and how they are triggered. It also provides examples to illustrate the concepts of delay and conduction angles, and how to analyze circuits to determine trigger angles.
