An air insulated linear pulse transformer for electrodischarge technology

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 similar to 500 MW at a matched load with a charge voltage 50 kV. The transformer transferred similar to 60% of the stored energy to the load over a characteristic time of about 1 mu s. The scalability the generator was studied by connecting two identical transformers in series which gave a power output of similar to 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.
