Abstract: A chain of series-connected semiconductor rectifiers has a voltage divider connected in parallel therewith. A firing circuit is connected on the one hand to the control electrode and to one of the main electrodes of each rectifier and on the other hand to two different points on the voltage divider. The firing circuit derives a control voltage between such points, which is fed to the rectifier by a switching means, such as an optically controlled semiconductor.
