Power Electronics Research Group

Research in the Power Electronics Group is focused on the development and experimental validation of new state of the art power electronic converters for such demanding applications as rolling stock, automotive, telecom and renewable energy systems. Key research directions include synthesis of new converter topologies, development of special control and protection algorithms, implementation of new components and elaboration of design guidelines to further improve the efficiency, power density, reliability and flexibility of the on-market power electronic converters. Other research activities are concentrated on the development of power flow  control algorithms and new supervision, fault detection, protection and communication methods for the electronic power distribution networks (Micro- and SmartGrids).
