Abstract: The phase control arrangement of a valve converter according to the invention comprises a control signal former having one input connected to the valve converter and another input connected to a reference signal unit. The output pulse from the control signal former is fed, concurrently with the output signal of a sawtooth oscillator, to a zero element having its output connected, via a phase limiter, to the input of the control pulse generator. Control pulses are distributed among the converter valves by means of a pulse distributor. The sawtooth oscillator has two inputs of which one is connected to the input of the pulse distributor and the other is connected to the output of the control signal former. The arrangement provides for correspondence of performance parameters of the converter to the preset values and maximum response speed in transient conditions.
