Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Aim. Development of powerful current radio pulses generators (CRPG) for powering high-frequency electromechanical
transducers based on IGBT transistors. Methodology. To carry out the research, the statements of the magnetic and
electromagnetic fields interaction with electric and ferromagnetic material, electric circuits, structure of radio electronic devices
theory were used. Results. The main provisions for creating powerful broadband generators for powering electromechanical
transducers based on IGBT transistors are determined. It is shown that the generators intended for use in measurements, testing
and diagnostics should provide adjustment of the frequency and duration of the output current pulses, and also provide current in
the transducer inductor of several hundred amperes. The connection between the power frequency of the resonant
electromechanical transducer and the gap between the transducer and the surface of the metal being diagnosed is established. A
CRPG variant for powering electromechanical transducers in the frequency range 1 ... 3 MHz and the duration of current pulses
of 1 ... 20 periods of the filling frequency is developed and manufactured. The peak current in the inductor of a high-frequency
electromechanical transducer has reached 450 A. Novelty. For the first time, the possibility of using powerful IGBT transistors in
electronic devices working in a key mode in push-pull circuits for feeding high-frequency electromechanical transducers is
shown. Practical value. Using the results obtained will allow the creation of new instruments for measurement, control and
diagnostics with wider characteristics. |
