ABSTRACT
The functional and structural circuits of an au-tomatic system for temperature control of power devices of a traction semiconductor converter of frequency are developed. The peculiarities of power devices as an object of temperature control are considered, an equivalent circuit of thermal processes substitution in semiconductor keys is offered, a comparative assessment of capacity of power loss in two- and three-level inverters of voltage is carried out. The dynamic properties of an electro-drive of a cooling fan with an asynchronous motor with a system of scalar control are analyzed. The recommendations on choice and computation of temperature control are developed.
KEYWORDS
traction electro-drive, transistor, diode, temperature, control system, equivalent circuit of substitution, scalar control, commutation frequency.

Editor-in-chief  of the journal  Bulletin of Bryansk State Technical University  KHANDOZHKO ALEKSANDER VLADIMIROVICH     Aleksander Vladimirovich Khandozhko is Doctor of Engineering (2002), Associate Professor (1993), Honorary Worker of Higher Professional Education of the Russian Federation, Professor of the Department of Metal-cutting Machines and Tools at Bryansk State Technical University (BSTU). He was born in Chelyabinsk in 1958. In 1980 he graduated from Bryansk Institute of Transport Engineering (BITE) (now - Bryansk State Technical University, BSTU) with a degree in Mechanical Engineering Technology, Metal-cutting Machines and Tools. From 1980 to 1983, he worked as a manufacturing engineer at an industrial enterprise. From 1983 until now he has been working at Bryansk State Technical University, having started his career at the university as a training master. In 1985 he entered the full-time postgraduate course in BITE. In 1989 he defended the thesis for the degree of Candidate of Science in the Dissertation Council of Moscow State Aviation Technological Institute (MSATI) on the specialty Heat Engines of Aircrafts. After defending his thesis, he worked as an assistant and then as an associate professor of the department of Metal-cutting Machines and Tools at BITE. In 2000 he entered the post-doctoral program and in 2002 he defended his doctoral thesis on the specialty of Technology and Equipment of Mechanical and Physical-technical Processing. After defending his thesis, he worked as a professor of the department until 2009. In 2009 he was appointed the head of the department of Metal-cutting Machines and Tools at Bryansk State Technical University. In 2016 when the laboratory of wave deformation and combined hardening in additive and subtractive technologies was founded at BSTU, he became the head of the department of modular technological equipment, continuing his teaching work as a professor of the department of Metal-cutting Machines and Tools. Khandozhko A.V. is a member of the editorial board of the journal Science Intensive Technologies in Mechanical Engineering (Bryansk). Since 2002 he has been a member of dissertation councils of several universities; currently he is a member of three dissertation councils D999. 155. 03, D999.112.02 and D212.021.03 aa well as being the Deputy Chairman of Dissertation Council D999.155.03.   Topics of scientific research 1. Fundamental theoretical and applied issues of designing cutting tools. 2. Theory and practice of designing and manufacturing process equipment, including for additive-subtractive processes. 3. Issues of mechanical processing of materials. 4. Problems of providing product quality in mechanical processing and additive processes.
