Academic and Research Laboratory of Theoretical Fundamentals of Electrical Engineering
At the Academic and Research Laboratory of Theoretical Fundamentals of Electrical Engineering, a multidisciplinary academic and laboratory complex ‘Theoretical Fundamentals of Electrical Engineering’ has been created for students studying at the technical faculties of LETI.
The academic and laboratory complex includes:
- a classical laboratory with real devices and electrical circuits;
- a stand laboratory with digital information processing;
- a center of computer technologies in electrical engineering;
- a laboratory on electromagnetic field theory with unique works for each group of students.
In a classical laboratory, the work is carried out on the plants produced using real elements, power supplies, signal generators, and measuring devices. Each plant consists of a laboratory stand with a set of devices and a set of models (circuit boards) with circuit elements placed on them. Students assemble the studied circuit and connect the necessary devices to it using connecting wires with single-pole plugs. A set of laboratory models allows for studying various types of circuits and observing the processes in them. The results of the experiment are recorded in the form of tables of measurements and oscillograms.
The stand laboratory work is carried out on 15 stands, where the studied circuits, consisting of real elements, are switched by keys that are controlled by buttons on the front panel. All voltages and currents are set and controlled by a digital display and an external oscilloscope. The computer-based laboratory work is carried out at the Center of Computer Technologies in Electrical Engineering, using Multisim v.10 and Labview v.8.2 software tools of the National Instrument Corporation. All laboratory works have electronic versions of methodological guidelines.
At the Center of Computer Technologies in Electrical Engineering, based on the Mathcad and Multisim packages, students are taught how to write coursework on modeling electrical circuits.
The cycle of laboratory work of the Theoretical Fundamentals of Electrical Engineering course is focused on working in the LabView system in the experiment simulation mode. Input signals, external devices, objects of research and control, measuring installations, etc. are modeled using the LabView package, taking into consideration the features of real processes.
In the Multisim environment, circuits are made up of virtual element symbols, and their structure is changed by keys controlled using the computer keyboard. Master oscillators and measuring devices have front panels of real devices. It allows students to impart skills to work with them.
A set of laboratory works has been developed at the Department of Theoretical Fundamentals of Electrical Engineering. It uses computer simulation of electrical circuits based on digital information processing with LabVIEW software.
The department also developed a laboratory practice on the theory of the electromagnetic field. The electromagnetic field laboratory of the Department of Theoretical Fundamentals of Electrical Engineering is fitted with devices that allow bachelor's and master’s degree students to measure the intensity of real physical models in a wide frequency range from 0.1 Hz to 10 GHz.
