CONTROLLABLE SINGLE USE COMMUTATOR Russian patent published in 2007 - IPC H01H79/00 

FIELD: electronics.

SUBSTANCE: controllable single use commutator contains a shorting device in form of semiconductor transformable structure. By first output it is connected to first bus of power supply, by second output through a load - to second bus of power supply. Device also contains control block made in form of alternating voltage generator, first output clamp of which through a key is connected to first output of shorting device. Shorting device is made in form of diode transformable structure and serially connected inductive element and capacitor, in parallel to which diode transformable structure is installed, connection point of first clamp of which to first clamp of capacitor is connected to first clamp of shorting device, second clamp of which is connected to second clamp of inductive element. Second output clamp of alternating voltage generator is connected to second bus of power supply.

EFFECT: simplified design, possible control over shorting device by means of relatively low power signal fed into force circuit.
