Abstract

A load-switching circuit for a tapped transformer utilizes identical netws of antiparallel thyristors bridged by commutating networks having a condenser in series with a damping impedance. According to the invention, the blocking of one pair of thyristors causes the energization of a relay to operate a switch contact shunting the damping impedance of the blocking pair so that its condenser functions as a voltage spike surge suppressor.
