“…A technology based on the use of high-voltage electric pulses in a liquid medium (electrodischarge technology) is actively and successfully investigated as an alternative to the traditional mechanical technology of destruction and grinding of composite materials [1][2][3][4][5][6][7][8][9][10]. A critical element of electrodischarge technology is the high-voltage pulse-periodic generator used to power the discharge, since the requirements for the parameters of such a generator are quite stringent.…”

A linear pulse transformer with air insulation at atmospheric pressure was created and tested under both constant resistance and non linear loads. The maximum power of the transformer output pulse reached ∼500 MW at a matched load with a charge voltage 50 kV. The transformer transferred ∼60% of the stored energy to the load over a characteristic time of about 1 μs. The scalability the generator was studied by connecting two identical transformers in series which gave a power output of ∼850 MW with doubled output voltage and reduced current. The frequency mode of operation was studied using one and two transformers with a charge voltage of 50 kV and a load that was, close to matched. In both cases, the power maximum and jitter showed no significant changes at any of the frequencies tested (up to 5 Hz). These results mean that the use of this generator can be recommended for a wide field of applications due to its scalability and low internal impedance.
