Compact repetitive high voltage nanosecond pulse generator

The application of nanosecond discharge plasma in many fields depends greatly on a compact repetitive high voltage nanosecond pulse generator. In this paper, a compact high voltage nanosecond pulse generator is presented, which is constructed with all-solid-state components. The pulse generator consists of DC module, insulated-gate bipolar transistors and its drivers, saturable pulse transformer and magnetic switch and so on. Simulation analysis and experimental investigation show that, the pulse generator can output pulsed voltage of 40 kV with duration about 100 ns and rise-time of 50 ns. Its highest repetitive frequency can be up to 5 kHz. (authors)
