CHARGING DEVICE OF CAPACITIVE ENERGY STORAGE Russian patent published in 2016 - IPC H03K3/53 

FIELD: physics.

SUBSTANCE: invention relates to charging devices of capacitive energy storage units and can be used in high-voltage electrophysical plants of high capacity with high level of accumulated energy. In the charging device of a capacitive energy storage containing an input three-phase bridge rectifier, a LC-filter, a charging converter with dosing capacitors, an output voltage sensor there is an additional capacitor filter, a transistor shunted by a reverse diode and a resistor, a transistor control driver, a RS-trigger, a 2AND-NOT logical element, two comparators, as well as a setting voltage source and a reverse diode voltage sensor.

EFFECT: adding these elements allows improving reliability of the charging device and enlarging its functional capabilities.
