STORAGE CAPACITOR CHARGE ARRANGEMENT Russian patent published in 2014 - IPC H02J7/10 

FIELD: electricity.

SUBSTANCE: use of the invention: in electrical engineering. To a storage capacitor charge arrangement including a three-phase power supply unit, three current-limiting dosing elements in the form of inductance coils, a three-phase bridge converter in the form of an independent voltage inverter, a storage capacitor, a control unit, a three-phase supply voltage sensor, phase current sensors, a storage capacitor voltage sensor, a unit for setting a voltage value of the capacitor, a unit for setting a charging rate of the capacitor, there introduced is a charging current controller of the storage capacitor, a phase synchronisation unit, a phase voltage converter, a phase current converter, a comparison unit, with that, to outputs of a three-phase line voltage sensor there connected are inputs of the phase voltage converter, the outputs of which are connected to inputs of the phase synchronisation unit, the output of which is connected to the input of the phase current converter, the output of which is connected to the input of the comparison unit, the output of which is connected to the input of the control unit, the output of the capacitor voltage sensor and the output of the unit for setting the voltage value of the capacitor are connected to the input of the controller, the output of which is connected to the input of the phase current converter, and outputs of the phase current sensors are connected to the inputs of the comparison unit.

EFFECT: improving the charge efficiency.
