The group has a unique laboratories. In the existing premisies of the Faculty of Electrical Engineering are several research and development laboratories - the so-called "light lab". These laboratories are equipped with modern measuring technology, top power source and load and test equipment, experiments are carried out on drives with outputs in the order of 50 kW with a maximum voltage up to 1000V.
In the near future, the group will significantly expand the laboratories. New laboratories RICE and a unique indoor laboratory testing and high-power electronics and transportation equipment are uder construction. In this new labs we will be able to develop and test equipment up to power of 4 MW and up to 31 kVrms voltage.

These software tools are top level equipment for simulation and precise tune of designed algorithm. This simulation are able discover physical principle of reserched topic. These principle are used for design of control strategies that are used for fast implementation into control system.
Power semiconductor converter for research
The group use own designed power converter for the research of new control of drives and power converters. These converters are based on IGBT, IGCT, MOSFET, SiC and JFET technologies. We are able to design diferent type of converter structures (two and multilevel inverters and active rectifiers, DC-DC converter). Power converters are controled with own designed control system. Designed converter are modular and they are used for several drive structer application.
Electrical machine sets
The group has wide portfolio of electrical machine sets that are properly assembled into sets and used to test new drives for testing of advanced control algorithms. It is possible to test completely new drive in laboratory conditions and properly tune its behaviour before it is put into operation in vehicles or in industrial and power drive systems.
