LOAD CAPACITOR CHARGE CURRENT LIMITING DEVICE AT CONNECTION TO AC NETWORK Russian patent published in 2016 - IPC H02H7/16 H02H9/02 

Abstract RU 2604883 C1

FIELD: electrical engineering.

SUBSTANCE: invention can be applied to electrical engineering. For this purpose, charging current limitation device contains following elements: first rectifier, second controlled rectifier on thyristors, current setting device, current controller, current measuring transducer, sawtooth generator, comparator, galvanic isolation device, isolating diodes and limiting resistors in thyristor control circuits, load capacitor connection terminals.

EFFECT: technical result consists in increasing of reliability due to reduced current loads on feeding AC voltage source and load capacitor both during device switching on, and in device reloading modes by its output.
