    the outputs of which are connected to the inputs of the output pulse control amplifiers.
    In order to extend the range of phase-out control pulses, the control pulse control unit is equipped with an additional delay element and additional two-input logic circuits AND by the number of converter pulses, the output of the delay element being connected via an additional delay element to the first inputs of additional logic circuits and the second inputs of which are connected to the outputs of the pulse-phase control unit, and the outputs of the additional circuits AND are connected to the second inputs of the logic circuits LEE.
    In addition, the phase adjustment unit is designed as a phase detector, a low-pass filter and a controlled oscillator, the first input of the phase detector being the input of the balancing unit and connected to the output of the delay element, and the output of the phase detector through the low-pass filter and the controlled oscillator are connected to its second input, which is at the same time the output of the pulse balancing control block.
    FIG. 1 p) and a diagram of the device for controlling a static multi-pulse converter; in fig. 2 - time diagrams that show his work.
    FIG. 1 and 2 denote pulse phase control unit 1, output amplifiers 2 control pulses, control impulse balancing unit 3, control impulse summing unit 4, delay element 5, phase adjusting unit b, two-input logic circuits AND 7-12 two-input logic circuits OR 1318, additional delay element 19, additional two-input logic circuits AND 20-25, phase detector 26, low-pass filter 27, controlled oscillator 28, pulses 29-34 at the output of the pulse-phase control unit, pulses 35 at the output b summing eye 4, pulses 36 at the output of the delay element 5, the pulses at the output 37 of the complementary element 19 delays internals 33 and 39 delay the output elements 5 and 19.
    The device works as follows.
    Pulse-phase control unit 1 generates control pulses that have asymmetry. This sequence of control pulses from all outputs is assembled by summation unit 4 and delayed by element 5 over a time interval 38. The delayed sequence of pulses 36 is fed to the input of phase trimming unit 6, which forms a sequence of control pulses with equal distances between the leading edges of the pulses, i.e. . control pulses are balanced.
    The pulses from block 1 are fed to the first inputs of the AND 7-12 circuits, which have some AC / 1 metry, but they cannot pass to the input of the amplifiers 2 without simultaneously receiving the Pulses to the second inputs of these circuits. Thus, the symmetry of the control pulses is determined by a sequence of pulses arriving at the second inputs of the circuits And 7-12 from the output of block 6.
    With fast regulation, shifting the sequence of pulses to the left, the balancing unit 3 delays the control channel. In order to increase the speed of the device without narrowing the range in which the sig / metric needles are produced, an additional delay element and additional AND 20-25 circuits are provided. In the established mode, control pulses 37 at the output of an additional delay element 19 arrive at the second inputs of the OR circuits 13-18 through AND 20-25 circuits later in the time of the main balanced pulses and do not affect the inputs of the amplifiers 2. With fast control in the direction of the advance to the right the elements first form control pulses at the input of amplifiers 2.
    The use of the invention will improve the accuracy of the phase adjustment of the control pulses and expand the range of symmetrization in devices for controlling a static multi-pulse converter.
