zündschaltungsanordnung in series high voltage thyristors.

摘要

A converting circuit adapted to be used at each end of a high voltage direct current transmission line. The circuit comprises a plurality of power thyristors connected in series, a resistor shunts each thyristor, a rectifying bridge made up of diodes is connected at the terminals of each thyristor for charging capacitive means when the thyristor is not conducting. The energy stored in the capacitive means initiates the thyristors through opto-electronic elements of a low power in response to radiant energy.
