Program-controlled pulse generator for repetitive nanosecond-pulse source

This paper introduces a type of program-controlled pulse generator, which can adjust the amplitude, width and frequency of the output pulses, and precisely control the delay time of the ten-channel output pulsesequences. The pulse generator includes the main and auxiliary power supplies, power amplifier circuit, controlling system, digital keyboard and liquid crystal display. The output pulses have parameters adjustable within following ranges: frequency range 1 Hz-30 kHz, pulse width range 1-30 s, and pulse amplitude range 1-15 V; the delay of ten branches can be precisely adjusted within 0-1 ms. The pulse generator can provide delay triggers for pulse sources in parallel, and synchronized triggers for IGBT switches in series.
