TRANSMISSION SIGNAL FORMER (VERSIONS) AND METHOD OF FORMING TRANSMISSION SIGNAL Russian patent published in 2013 - IPC G05D19/02 H02P13/00 

FIELD: physics.

SUBSTANCE: disclosed is a transmission signal former, said signal being transmitted to a transformer, having at the primary side symmetric power connection points and a centre tap, having: a contact for feeding the actual signal as a current metric, passing through the centre tap of the transformer, a subtraction circuit for generating a difference signal depending on the actual signal and a given signal, a multiplexer configured to transmit the difference signal for different sub-periods of the transmission signal to its different outputs, on one controlled current sink for each output of the multiplexer. The control input of the current sink is connected to the corresponding output of the multiplexer to convert the difference signal in a current signal, on one contact for each current sink to output current signals to control inputs of current-controlled current sources, the main current circuits of which are connected to the corresponding symmetrical power connection points of the transformer.

EFFECT: enabling control of current signals transmitted to a transformer.
