Abstract

Device for distribution of currents for current rectifying units, especially for those formed from a plurality of rectifiers controlled, coupled in parallel, of which one of them works as a pilot; essentially, it is characterized by being constituted by an electronic circuit comprising three information inputs and an output for a control signal, one of the inputs receiving a signal proportional to the intensity that circulates through the pilot rectifier, which is connected through a adjustable attenuator to one of the inputs of an operational amplifier, which receive at its other input, and after passing through an attenuator stage, a signal proportional to the current flowing through the rectifiers, the output of said operational amplifier being, connected to the base circuit of a transistor, whose collector is associated together with a signal attenuator and with an input of a second operational amplifier that, at its other input, receives the control signal from the pilot rectifier and provides a signal at its output suitable for controlling the driving angle of the unit's rectifiers.
