Summary
Development and mastering of manufacturing of small-sized highly reliable new generation welding machine featuring high-frequency transformer on the basis of composite low-coercitivity MIM-material. The machine under development is meant for conducting welding operations at industrial enterprises and by individuals.
Description
Development of a reliable patently-clean inverting device
featuring high-frequency transformer on the basis of composite low-coercitivity
MIM-material. The research on creating of a crucially innovative patently-clean
composite low-coercitivity material held by the Institute of Solid Bodies
Physics and Semiconductors (National Academy of Sciences of Belarus) and
scientific-production firm “Dipol” proved the possibility of successful
solving of the stated issue. The developed composite material with saturation
induction of about 2 T, Curie temperature of over 800 °C operating at the
frequency range of 50–100 kHz allows to eliminate all the stated
disadvantages of the existing inverting devices. A possibility of a transformer
made with the use of the proposed composite material to come out to saturation
at the operating mode of the core 0.3–0.5 T is absolutely impossible.
As opposed to ferrite cores devices, the inverting device being developed
ensures 100% powering at any capacity. This inverting device featuring a
high-frequency transformer on the basis of a composite magnetic material
protected by international patents is a patently-clean product and can be sold
in any country.
In the process of project implementation it is planned to carry out works on
optimizing the energy conversion device that includes interfacing of parameters
of the high-frequency transformer based on composite magnetic material and
those of the power transistor switches. The processor-based system for
controlling power transistor switches that determines welding conditions is
planned to be developed. The major part of the work relates to optimization of
the welding process on AC- and DC-current in manual/ automatic mode,
elaboration of breadboard and test models, certification and organization of
production at SPF “Dipol” facilities in Vitebsk.
