E 2.4.1.2 Energoelektronika, zestaw edukacyjny COM3LAB

The COM3LAB courses on power electronics convey the topic in concentrated form to deepen understanding. Characteristics of power semiconductors and the basic standard circuits are investigated. All the experiments work with single-phase safety extra-low voltage, which is non-hazardous. Only small amounts of materials and little space are needed for the experiments. A student desk with a PC is entirely sufficient.

Objectives

• Basic physical principles of power semiconductors
• Design of key basic circuits for power electronics
• Assessment of properties of rectifiers and converters

The equipment set allows students to experiment themselves in a lab equipped with PCs using safety extra-low voltage, which presents no hazard. It is also suitable for demonstration experiments by teachers. Multimedia software explains and monitors how the experiments are carried out.

The target group mainly consists of trainee industrial or jobbing electricians. The systems can also be used for vocational further education.

To gain a deeper understanding, experiments with the compact system E2.4.2.1, Static converter valves, is ideal.

In project lessons an asynchronous machine (732 104) is operated without a load and supplied with three-phase power (3 x 230 V) via a universal converter (735 297). The parameters for the converter can be set via an interface panel on the board itself which connects directly to the COM3LAB course.
