Repetitive frequency pulse based on hydrogen thyratron inductive-adder

A high voltage repetition pulse output based on the application of the hydrogen thyratron coupling with inductive-adder is proposed and the magnetic distribution with coaxial shielding structure is analyzed. The amplitude of working voltage is 25 kV, the repetitive frequency of pulse waveform is 20 Hz and the trigger delay of grids is 5 ns due to the differences of the devices parameters. The experiment results show that the hydrogen thyratron trigger is stable and reliable, and the application of the inductive-adder output mode based on the coaxial shielding has less impact on the reliability and the rising edge of the output pulse waveform and the amplitude of output pulse is about 50 kV, and the feasibility of inductive-adder technique applied in gas switch is confirmed.
