DEVICE FOR ARC-LESS COMMUTATION OF ELECTRICAL CIRCUIT Russian patent published in 2006 - IPC H01H9/30 

FIELD: engineering of networks of autonomous electricity provision systems.

SUBSTANCE: device for arc-less commutation of electric circuit, contains normally open controllable semiconductor key, controlling electrode of which is connected to first outputs of resistor and direct-enabled diode, capacitor and contacts, first output of which is connected to first output clamp, and second one - to second output of resistor and to first force output of semiconductor key, forming controlling input of key together with controlling electrode, second force output of which forms second output clamp, capacitor by one end is connected to first output of contacts, and by another one - to second output of direct-enabled diode and to first output of additionally inserted resistor, second output of which is connected to second output of contacts.

EFFECT: provision in disabled state of galvanic decoupling of load from power source.
