A 100 kJ Pulse Unit for Electromagnetic Forming of Large Area Sheet Metals — •Werner Hartmann1, M. Römheld1, and A. Donner2 — 1Siemens AG, Corporate Technology, CT PS 5, Erlangen, Germany — 2Siemens AG, Automation and Drives, A&D MC RD 8, Chemnitz, Germany
We report on the development of a pulse generator for peak currents of up to 200 kA at a pulse width of typically around 100 µs, depending on the load parameters. Maximum pulse energy is 100 kJ. The short circuit current handling capability of peak currents of up to 450 kA is a major issue in the pulse generator design.
A modular, 3-branch design of parallel capacitor banks has been adopted to achieve the requirements concerning reliability, lifetime, and short circuit capability. The prototype pulse generator is based upon off-the-shelf devices, including the high-current semiconductor switches.
The pulse generator has been tested successfully at pulse energies up to 80 kJ. First operating results of the commissioning phase of the installation are reported.
