Power Devices (A8206)

In Electrical Engineering

About this class



Learn the principles of AC/DC and solid-state theories.? Digital electronic theory is also introduced.




Prerequisites


This lesson is designed for participants familiar with AC/DC theory, electrical safety, electrical print reading, electrical connections, semiconductors and diodes. The ability to use electrical test instruments is also required.

Description


This lesson describes the operating principles and function of transistors, SCR??S, and triacs and shows how current flows through each device. Schematic symbols for transistors, SCR??S, and triacs are also shown and explained.

Objectives


Describe the switching and amplification functions as well as the three regions of a transistor. Identify the schematic symbols for PNP and NPN transistors and explain how current flows through each type. Explain how transistors perform switching and amplification functions. Use an ohmmeter to test a transistor. Identify the schematic symbols for a SCR and a triac and explain how they operate.
