Alexander B. Kosarev – Dr. of Sc. (Engineering), Professor, First Deputy General Director of the Railway Research Institute.

Biography

Alexander B. Kosarev graduated the Railway Transport Engineering Institute, Railway Electrification Faculty in 1986. After graduating, he began to work in the All-Russian Railway Research Institute. Не successfully completed his Ph.D. thesis "Electromagnetic compatibility of low-voltage networks and adjacent metal communications with a traction power supply system with its amplifying" in 1991. Alexander B. Kosarev completed his doctoral thesis "Methods and means of the ensuring environmental safety in the zones of electromagnetic influence of electrified AC railways" in 1999. In 2007 he became the professor.

In his professional sphere, he passed all the qualification levels: from a junior researcher to the First Deputy General Director.

Main research interests

The main scientific research sphere is the power supply systems of railway transport, as well as the improvement of transport technologies and technical means of the railway and machine-building industries. The priority is the research, practical and management activities’ integration in the Railway Research Institute.

Alexander B. Kosarev has about 200 scientific publications, including 25 patents and 2 monographs.

Alexander B. Kosarev contributed to the development of the environmental safety concept in the electromagnetic influence zones of electrified railways. He developed methods and means of the environmental safety considering traction networks as circuits with variable parameters of the arbitrary soil geoelectric structure. He also proposed an integral system of the traction power supply with environmentally friendly electromagnetic influence.
