50 kJ ultra-compact pulsed power supply unit for various applications

During the last years modular structured energy packs have been built up at ISL as a basic installation for various applications in the field of pulsed power electronics. Each power supply module comprises one energy storage capacitor, a thyristor stack, a corresponding number of crowbar diodes and a well-designed coaxial power line serving as a pulse forming network and current limiting reactor. The paper presented here describes the basic design of the 50 kJ energy pack, a further developed set-up with a reduced overall height obtained by using a novel multichip thyristor and the broad field of applications for such high-power supply units
