The COM4LAB course entitled “Electronic Components II” is the second course concerning the active electronic components that have an amplifying effect or permit control. Special transistor types and semiconductors from the power electronics sector are used. One of their main applications, phase angle control, is examined taking the thyristor and the TRIAC as examples. The students are instructed on how to use the function generator, oscilloscope and multimeters. The course comprises 14 chapters.
Total duration: Up to 5 hours
Target audience
Among others, the course can be used to support the training process for the following professions:
- information electronics technician
- system electronics technician
Learning objectives
The students should:
- understand the setup, function and use of field-effect transistors, MOSFETs, IGBTs, DIACS, Thyristors and TRIACS and
- be able to record characteristics of these active components with an oscilloscope.
Topics
The course covers the following topics:
- field-effect transistors
transfer characteristic of the JFET – output characteristic family of the JFET – JFET as switch
- MOSFET
characteristics – MOSFET as switch
- IGBT
characteristics – IGBT as switch
- DIAC
- thyristor
characteristic – thyristor in a DC circuit – phase angle control with a thyristor
- TRIAC
