ABSTRACT:
A gate pulse generator for a reactive power compensation device in which a capacitor is connected in series with antiparallel connected thyristors and which is so constructed that triggering pulses are produced and current is passed into said capacitor when both a signal of forward voltage imposed on said thyristors and a thyristor conduction period signal that is reset by a phase control signal are present. The gate pulse generator includes a means by which conduction period signals associated with thyristors of one polarity are reset during conduction if both a triggering pulse of thyristors of the opposite polarity and a delayed phase control signal associated with the opposite polarity thyristor is present.
