Abstract
A device supplies electric energy for projectile detonators without a battery or additional energy generation during flight of the projectile. For operating the projectile detonator in the flight phase, a supply capacitor charged during an inductive programming phase is disposed. The capacitor has a very low leakage current in order to bridge a time in the range of minutes between the programming and the start of the flight phase without significant energy loss. The charging of the supply capacitor takes place through halfwaves, of a programming AC voltage not utilized in the programming and not under load.
