Abstract: Energy-supply systems that supply energy in the power range of a few Megawatts (MW) to Gigawatts (GW) within a pulse duration of a few milliseconds (ms) are referred to as pulse-current supplies. Such known energy supply system primarily comprises a charging device for charging an energy store, a plurality of plate-type capacitors as energy stores, a high-power switch for releasing the stored energy, and a pulse-shaping device. The structural shape required for storing the energy in particular makes known pulse-current supplies highly complex, voluminous and costly. In contrast, the present invention involves using wound capacitors (20) and high-power switches (4) instead of conventional plate-type capacitors and high-power radio paths, which reduces the structural space requirement. The pulse shaping is effected by a toroidal coil (5) and a free-wheeling diode (3). Light-switched thyristors mounted in the free space (5.1) of the toroid coil (5) can preferably be used as high-power switches (4).
