Abstract

A device for the protection of an apparatus constituted by rectifying semiconductor elements, in which the pulse transformers comprise, on the one hand, magnetic circuits of substantially rectangular magnetization cycle, subjected to the currents in the semiconductor elements, and, on the other hand , detection windings mounted on magnetic circuits to emit an impulse that drives a relay, after a change in the direction of the current to which the corresponding magnetic circuit is subjected.
