Course Number: VEE222

Course Title: Discrete Devices II

STUDENT LEARNING OUTCOMES 

General Objective

This course will introduce students to the thyristor power control family of semiconductor devices and other power control and triggering devices. The student will describe the construction and operation of various devices as well as observe their operation.

Specific Objectives

Students will be able to:

1. describe the purpose and operating characteristics of UJTs and SCRs.
2. describe UJT oscillator operation.
3. describe SCR trigger circuit operation.
4. describe SCR power control operation.
5. perform SCR circuit troubleshooting.
6. describe the relationship between Triacs and SCRs, and Diacs and Four-layer devices.  Observe the effect of DC and AC voltages on Triac operation.
7. describe the construction, operation and applications of PUT devices.
