A device for protecting delay-line modulators of this type by detecting turn-off of the discharge thyristor by a comparator so as to prevent closing of the charge thyristor as long as the discharge thyristor is in the conducting state. This has the effect of preventing short-circuiting of the feed source.

Device for protecting a delay-line modulator

The invention concerns a power modulator provided with a transformer. This transformer having a high transformation ratio receives a low voltage impulse and transforms it into a high voltage impulse directly applicable on a high frequency or hyperfrequency tube in order to create a powerful impulse magnetic field. The transformer is particularized by the realization of its primary composed of a plurality of primary windings, all of which are connected in parallel and which, put end to end, extend along the entire lengths of the secondary. They are wound furthermore around the secondary and not inside it.
