Abstract: In the effect experiments of the electrical power systems and the relay protection equipments,the high voltage repetition pulse with sub-microsecond arising time is one of the key equipments.A novel method for realizing high voltage repetition pulse output based on application of the hydrogen thyratron coupling with inductive-adder was proposed.The inductive-adder output mode has impact on the pulse arising edge,which was deduced and analyzed based on the transformer theory.The distribution of the repetitive pulse and the single pulse in frequency domain as well as the M-field was analyzed by means of simulation,and the design of the coaxial shielding structure was given in this paper.The repetition frequency pulse with the amplitude of 50kV,the continuous 5-way pulses and the arising time of less than 20ns,can be obtained by using this kind of novel design.The minimum gap of the pulse is 50μs with a continuous regulation interval of 10μs.The experimental results show that the hydrogen thyratron trigger is stable and reliable,and the application of the inductive-adder output mode based on the coaxial configuration is also the effective solution to lessen the impact on the arising time edge caused by the leaking inductance,which results in a better transmission efficiency.
