Project description

This project comes under a support program for dual innovation (RAPID),  which consists in supporting industrial research projects or experimental development projects with a high technological potential that could have both military and civil applications. In partnership with the company EFFITECH (project owner), the aim of the project is to develop two original architectures capable of producing high-voltage and high-power – from 1 MW to 1 GW – electrical pulses. The rectangular pulses generated are suitable for a wide range of applications and offer a much better cost-performance ratio than current technologies. The PhD conducted by F. Allard, started in 2014, is associated with this project.

Two innovative architectures are being studied to remedy the shortcomings of conventional architectures:

  • The first comprises a series/parallel assembly of resonating modules, optimized to operate in a pulse regime at a high resonance frequency to reach peak powers of up to 10 MW.
  • The second is organized around a very high-voltage multi-pulse transformer. The pulse attacking the transformer is produced by synchronizing shaped rectangular pulses (Blumlein structures).

Ultimately, the research work divided into two themes should serve to validate a large number of latest-generation semiconductor switches (MOSFET SiC 1000V/1500A, IGBT 1200V/700A) and the pulse transformer technology able to provide very high voltages (up to 600 kV) and generate pulses in the range of 100 MW to 1 GW.
