Optocouplers and IGBTs

Optocoupler
In this lab, students will be looking at two devices used as electronic switches: optocouplers and insulated-gate bipolar transistors (IGBTs). First, students will investigate the theory and behavior of optocouplers. Students will use optocouplers digitally and in a real circuit to control a high power loop from a low power loop. Students will also learn about IGBTs. First, students will look at detailed theory of optocouplers and IGBTs. They will then explore the importance of both electric devices. Finally, students will examine specific uses of optocouplers and IGBTs in real-world examples and answer short answer questions.
