Die Fig. 4 zeigt die niederfrequente sowie die resultierende Steuerspannung, bestehend aus einer höherfrequenten und einer überlagerten gleichfrequenten und phasengleichen Spannungswelle spitzer Kurvenform für ein Sechsphasen-Drehstromnetz. Die Schnittpunkt der niederfrequenten Steuerspannung mit der spitzförmigen höherfrequenten Steuerspannung zeigen deutlich, dass die Zündmomente der einzelnen Anoden einwandfrei festgelegt sind. Durch diese spitzförmige höherfrequente Steuerspannung ist ein sicheres Zünden der Anoden immer gewährleistet.
PATENT-ANSPRÜCHE :
1. Einrichtung zum Steuern der Gitter von Umrichtern zur Umformung von Mehrphasenstrom höherer Frequenz in Wechselstrom niederer Frequenz und umgekehrt, bei denen die Gitter jedes Gleichrichters sowohl mit einer Betriebsspannung der höheren Frequenz als auch mit einer Spannung der kleineren Frequenz gesteuert werden, dadurch gekennzeichnet, dass der höher frequenten Komponente der dem Mehrphasennetz entnommenen sinusförmigen Gitterspannung eine gleichfrequente und phasengleiche Spannungswelle spitzer Kurvenform überlagert ist.

Device for controlling the grid of converters for converting higher multiphase currents
Frequency in alternating current of lower frequency and vice versa.
EMI1.1

4 shows the low-frequency and the resulting control voltage, consisting of a higher-frequency and a superimposed voltage wave of the same frequency and in phase with a sharp curve shape for a six-phase three-phase network. The point of intersection of the low-frequency control voltage with the pointed, higher-frequency control voltage clearly shows that the ignition moments of the individual anodes are properly defined. This sharp, higher-frequency control voltage ensures that the anodes are always ignited safely.
PATENT CLAIMS:
1. Device for controlling the grid of converters for converting polyphase current of higher frequency into alternating current of lower frequency and vice versa, in which the grid of each rectifier are controlled both with an operating voltage of the higher frequency and with a voltage of the lower frequency, characterized in that the higher-frequency component of the sinusoidal grid voltage taken from the multi-phase network is superimposed on a voltage wave of the same frequency and phase with a sharp curve shape.
