Institute of Electrical Engineering, Slovak Academy of Sciences

The Institute was established in 1953 as a governmental institution dedicated to the research in field of electrical machines and devices. Nowadays the activities are focused on the research and development of semiconductor, superconductor, oxide and magnetic materials and devices, including theoretical and experimental study of their structural, optical, transport properties and applications in devices for the information technology and power engineering. Researchers of the Institute implement international projects supported by EU, projects supported by ERDF, and national projects supported by APVV and VEGA agencies. The Institute

The superconductor research is centered on technology and testing of MgB2 and high-temperature superconducting tapes and conductors, and the participation on development of power devices, like  transmission cables, electromagnets, fault current limiters and transformers.
