The COM4LAB course entitled “AC Technology I” is the first course on the fundamentals of AC technology. It addresses the generation of AC voltage, and the functions of a transformer and various rectifier circuits are practically devised using a number of experiments. 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:
- electrical system fitter
- electronics technician for automation technology
- electronics technician for energy and building technology
- electronics technician for devices and systems
- electronics technician for information and system technology
- electronics technician for machine and drive technology
- aircraft electronics technician
- information electronics technician
- system electronics technician
Learning objectives
The students should be able to:
- understand the principle and function of a transformer,
- recognise the effects of various rectifier circuits and
- be able to use the function generator and the oscilloscope.
Topics
The course covers the following topics:
- generation of alternating voltage
step voltage – continuous alternating voltage – electronic generation of alternating voltage
- function generator and oscilloscope
- transformer
induction – principle of the transformer – short-circuited transformer – loaded transformer – transformer losses
- rectifier circuits
diode as a current valve – half-wave rectifier M1 – full-wave rectifier M2 – Graetz bridge rectifier B2 – symmetrical output voltage
Previous knowledge
The students do not need any previous knowledge of electrical engineering in order to be able to complete the course successfully. Dealing with simple formulas is, however, required.
