OPTIMIZATION OF HIGH-VOLTAGE NANOSECOND PULSE COMPRESSION
The work is directed on an increase in an energy effectiveness of the existing compact devices, intended for the energy compression of the nanosecond time range pulses. Devices consist of high impedance (HL) and forming (FL) lines and high-pressure spark gas discharger. In contrast to the device with a serial discharge circuit of FL, the version of circuit with a parallel discharge for the load of lines HL and FL is proposed.The calculations, which show the energy effectiveness of this scheme, are given. Converter with the parallel discharge circuit on base is developed. The converter with parallel discharge circuit increased peak pulse power additionally on 17％ in comparison with serial discharge converter for a case of initial pulse with rise time ~0.5ns. The voltage amplitude of the initial nanosecond pulse 4ns was increased from 145 kV to 195 kV (across the load 45 Ohm) with the time compression of pulse to ~0.8 ns. A real increase of the peak power across the load 45 Ohm reached 1.8 when calculated value 2.5. Device, which form two fixed pulse waveforms 210kV,0.8ns and 250kV, 0.45ns by converting nanosecond pulse with an amplitude 160 kV and peaked rise time to 0.3 ns is made.
