COMMUTATOR OF POWER SUPPLY BUSES Russian patent published in 2012 - IPC H03K17/13 

FIELD: electricity.

SUBSTANCE: commutator comprises a power electronic key, a comparator and a control unit with control inputs, an integrating link, the power electronic key comprises two controlled elements connected oppositely in series, a control input of the first controlled element and a control input of the second controlled element are connected to each other and form a control input of the electronic key, a power output of the first controlled element is connected to one of the power outputs of power supply buses commutator and with one of comparator inputs, the power output of the second controlled element is connected to the other power output of the power supply buses commutator and with the other input of the comparator, the comparator's output via serially connected control unit and integrating link is connected to the control input of the electronic key, at the same time the control unit may contain serially connected logical circuits OR, EXCLUSIVE OR and AND, the second inputs of which are connected to inputs of the control unit and form inputs of connection, inversion and disconnection of the electronic key.

EFFECT: improvement of operational properties, higher noise immunity and efficiency, expanded area of application.
