OPERATED STARTING DEVICE Russian patent published in 2021 - IPC G05F1/56 

FIELD: electrical engineering; radio engineering; hydroacoustics.

SUBSTANCE: invention relates to the field of electrical engineering, radio engineering and hydroacoustics and is intended for use in power supply devices for transmission paths with repeated short-term operating modes. A starting device with a direct current charge channel is proposed, containing a series-connected resistive current sensor (1) and a regulating element (2), which provide the mode of the current generator for charging the filter capacitance (6) when the load is disconnected. And there is also a parallel channel for switching the power supply voltage to the load in the nominal mode by an external control command after the completion of the charging mode, which includes a threshold amplifier (3) that compares the output signal of the sensor (1) with the voltage of the reference voltage source (4). There is an additional high-current regulating element (8) with an integrating circuit (9) by a control signal, the passage of which is allowed after the completion of the charging mode. In addition, there is a coincidence threshold element (10), which generates a control signal to turn on the load (7) after turning on the regulating element (8). The device implements an overload protection mode by the residual voltage of a high-current regulating element and provides a reverse diode (5) that simulates the load to close the output filter current after an emergency shutdown.

EFFECT: this allows minimizing energy losses and increasing the reliability of the controlled starting device, as well as ensuring its protection against overcurrent modes.
