A pulsed power system for generating multiple high voltage pulses with a short pulse repetition interval

A new type of multipulse generator is proposed for the generation of high power pulses with extremely short pulse repetition interval. In this system, an air-core step-up transformer is used with a magnetic switch and the pulse forming line is charged on a double resonance mode. Numerical simulations of the system have shown that 56 ns duration pulses matched to a 20 Ω impedance can be produced with a minimum pulse separation of 2.7 μs. The voltages and the efficiencies of the output pulses are 0.63 MV and 93% for the first pulse and 0.56 MV and 69% for the second pulse.
