Power Electronics Application Laboratory has been founded in 2005. Last fifteen years has been of key importance in power electronic applications development including power converters for fotovoltaic and wind energy conversion systems (WECS). Improved power converters could been found in electric drives including sophisticated applications in robotics or in hybrid vehicles.
Emerging technologies have been closely related with new algorithms for power electronic converters. In frame of power electronic laboratory students could apply existing control algorithms to power converters and developed the new ones.
Fig. 1. Measurement of power converter switching signals for different power converters
Transistor power converters have been in focus of development for several decades including the DC/DC and DC/AC power converters, however, lately a new types of AC/DC and AC/AC power converters apear.
