EPE Power electronics and didactically-optimized drives 300W
Power electronics is the technology of switching and converting high levels of electrical power. Today this is
done using semiconductor components like diodes, thyristors and IGBTs. The main area of application for power
electronics is drive technology. The modular training system accompanies you on your journey from static
converter technology to closed-loop control drives and offers you the possibility of dealing in detail with the
topics most relevant to you. The modular system with training panels and the systematic software support
allows for continuous upgrading, supplements or technology-prompted extensions.

The self-commutated power converter circuits training system makes
it possible to construct and investigate power electronics circuits
using IGBTs. In addition to the power semiconductors, the system
includes equipment for controlling and measuring all the relevant
variables. Operation and recording of measurements are carried
using virtual instruments. Alternatively, the system can be used
without a PC. The experiment instructions take the form of an
interactive multimedia course. The system can also be extended by
addition of a Matlab interface. This enables you to create your own
applications and test them using authentic hardware components.
The following circuits can be assembled:
Single-quadrant controller
4-quadrant controller
AC inverter
Three-phase inverter
Frequency converter drive
Variable speed DC drive
Servo drive
