E 2.4.1.1 Energoelektronika System Plug-in

The experiments are carried out using the STE plug-in system Electricity/Electronics.

Objectives

• Recognition of basic physical principles
• Implementation of electrical circuits according to circuit diagrams

The STE student experiments for power electronics investigate the characteristics of power semiconductors and basic standard circuits. All the experiments work with single-phase safety extra-low voltage, which is non-hazardous. Required previous knowledge includes AC technology, semiconductor technology and experience with handling an oscilloscope.

The target group is made up of students in general or vocational education. The experiments are designed as an introduction at a simple level of understanding.

To gain a deeper understanding, experiments with the compact system E2.4.2.1, static converter valves and the COM3LAB courses on power electronics are ideal.
