STARTING AND OPERATING CURRENT LIMITING DEVICE Russian patent published in 2022 - IPC H02H7/16 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering. Increased reliability is achieved by protecting the power source from overcurrent when connecting a capacitive load, as well as in case of an emergency increase in current in the load power circuits. To do this, a frequency-current limiter is introduced into the load power circuit, built on the basis of a transistor switch, a feedback signal comparator and an LC filter shunted by a diode.

EFFECT: increasing the reliability of electronic equipment and simplifying the electrical circuit.
