COM4LAB: AC Technology I


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

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.


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.
