ANTI-ARCING CIRCUIT Russian patent published in 2018 - IPC H02H9/00 H01H9/30 

FIELD: electrical engineering.

SUBSTANCE: power adapter comprises: a connector connectable to a client device; and an anti-arcing circuit configured to mitigate arcing during connection and disconnection of the connector to the client device by: operating in a detection mode that suppresses power supplied to the client device from a power source via the power adapter; monitoring to determine when a connection of the connector to the client device is established; in response to a determination that the connection of the connector to the client device is established, switching to an operational mode to supply a power level sufficient for operations of the client device; wherein the anti-arcing circuit includes a first current circuit associated with the detection mode and a second current circuit associated with the operation mode, wherein the first current circuit includes a first resistor and the second current circuit includes a second resistor, wherein the first resistor has a resistance to cause suppression of the power supplied to the client device from the power supply in the detection mode, and the second resistor has a resistance that is lower than the resistance of the first resistor to enable supply of a power level sufficient for operations of the client device in the operating mode, without significant loss of power.

EFFECT: technical result is improved safety and reliability of the power supply by suppressing arcing.
