On the morning of March 10, Vladimir Efanov, founder of FID GmbH, Germany, was invited to visit the Department of Electrical Engineering and delivered an academic report titled “Nanosecond pulse power technology: achievements and prospectives.” The report was chaired by Fu Yangyang, Associate Professor of the Department of Electrical Engineering, attended by relevant enterprise personnel and more than ten graduate students from the department.
Traditional high-voltage pulse technology using spark gaps and thyratrons suffers from limitations such as short lifespan, unstable switching, and low pulse repetition rates. In his report, Vladimir Efanov focused on nanosecond/picosecond pulse generation methods based on all-solid-state FID (Fast Ionization Device) and DRD (Drift Recovery Diode) semiconductor switches, systematically expounding key technical principles and cutting-edge advancements in this field. Nanosecond/picosecond pulse sources based on such all-solid-state switches are widely used in emerging interdisciplinary areas, including plasma-assisted flame and combustion treatment, polluted gas and liquid processing, gas-pumped laser drivers, biomedical electroporation, and agricultural and food processing. During the Q&A session, attending faculty and students actively raised questions on the core content of the report, engaging in a lively discussion with Vladimir Efanov on technical breakthroughs and detailed engineering applications.
Vladimir Efanov graduated from Leningrad Polytechnic Institute in 1981 with a degree in Semiconductor Device Physics. In 1986, he received a Doctorate in Physics/Mathematics from Peter the Great St. Petersburg Polytechnic University, with a doctoral dissertation titled “Research of non-stationary injection and dissipation processes of electron hole plasma in high electric fields and development of fast devices based on these processes.” From 1981 to 1999, he served as a senior researcher at the Ioffe Physical-Technical Institute. In 1998, he founded FID Technology in Russia, and in 2001, he founded FID GmbH in Germany.
