Abstract
The use of preliminary induction heating of the working zone of magnetic-pulse sheet metals working can improve its efficiency and expand the existing range of technological operations for contactless metal working. Integration of the induction heating systems requires the improvement of existing technical solutions for the electrical energy transformation and transmission. This work is devoted to the mathematical and experimental analysis of the physical processes in the electrical system of a step voltage converter, the technical realization of which is aimed to improve the qualitative and quantitative efficiency indicators of the magnetic pulse metals processing systems and induction heating systems. The novelty of the work is the development of a step charging system to be realized as a controlled source of electrical energy that is a self-contained unit allows to convert voltage levels. The method presented of the non-stationary transient process mathematical representation in the form of piecewise-continuous functions was confirmed experimentally. The experimental data obtained for the model sample of the voltage conversion system proposed was fully correspond to those of the values calculated, that is why the voltage converter is operable itself for using as previous charge systems for magnetic pulse metals processing using induction heating systems as an integrated auxiliary unit. The results of the studies conducted direct on the practical importance for the creation of more compact and automated systems for contactless metal processing.
