On the morning of March 10, Vladimir Efanov, Founder of FID GmbH Germany, was invited to visit the Department of Electrical Engineering and Applied Electronics (EEA) and delivered an academic lecture entitled Nanosecond pulse power technology: achievements and prospectives. The lecture was chaired by Associate Professor Fu Yangyang of EEA, with participants including professionals from relevant enterprises and more than ten postgraduate students of the department.
Traditional high-voltage pulse technologies using spark gaps and thyratrons have inherent limitations such as short service life, unstable switching performance and low pulse repetition rate. In his lecture, Vladimir Efanov focused on the nanosecond/picosecond pulse generation methods based on all-solid-state semiconductor switches of FID (Fast Ionization Device) and DRD (Drift Recovery Diode), and systematically elaborated on the key technical principles and cutting-edge progress in this field. Nanosecond/picosecond pulse sources based on such all-solid-state switches are widely applied in various cutting-edge interdisciplinary fields, including plasma-assisted flame and combustion, treatment of polluted gases and liquids, driving of gas-pumped lasers, biomedical electroporation, as well as agricultural and food processing. During the Q&A session, the attending faculty and students actively raised questions around the core content of the lecture, and held heated discussions with Vladimir Efanov on issues such as the breakthrough of technical difficulties and detailed engineering applications.
Vladimir Efanov graduated from the Leningrad Polytechnic Institute in 1981 with a degree in Semiconductor Device Physics. He obtained his PhD in Physics/Mathematics from the Peter the Great St. Petersburg Polytechnic University in 1986, with his 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. He served as a Senior Research Fellow at the Ioffe Physical and Technical Institute from 1981 to 1999. He founded FID Technology in Russia in 1998 and established FID GmbH in Germany in 2001.
