The object of research is high-voltage resonant charging systems of capacitive pulse current generators (PCG) energy storage devices for electric-discharge materials processing technologies. Research methods - mathematical modeling, computer modeling, physical experiment, experimental research. The principles of construction of resonant systems for charging capacitive energy storage devices (CESD) to high voltage have been developed, the implementation of which allows to increase the specific energy characteristics of the pulse current generator by 2-3 times. In particular, it was found that to achieve high voltage on the CESD it is necessary to use the voltage increase on the capacitor of the series resonant circuit relative to the supply voltage, and to reduce the charging time of the CESD, mass parameters of electromagnetic elements and current through transistors. to saturation frequency. According to the results of simulation, the criterion for determining the resonant frequency fsat, above which the charging current does not increase, is obtained. This criterion is the basis of the method of calculating the electrical parameters of the CESD charging system Product Description popup.authors Adamchuk Yuriy O.
