In this lab, students will be observing the operation and characteristics of thyristors. First, students will learn the theory of a thyristor. Then they will focus on seeing a thrysistor in simulation, followed by building one on a bread board, measuring data with an oscilloscope. Finally, students will explore a special type of thyristor called a TRIAC through simulation and answering short questions.


This is lab 7 of 14 in the course, Analog Electronics.


After completing this lab, students will be able to:
  1. Discuss the characteristics, operation, and application of Thyristors and TRIACs.
  2. Implement a safety circuit using a Thyristor and identify the triggering voltage and turn-off time.
  3. Compare the behaviors of Thyristors and TRIACs.
