Abstract :
High voltage nanosecond range repetitive pulse generators to generate pulsed corona streamer discharges for environmental applications are now being widely explored. Conventionally, pulse generators for these applications have been designed using high voltage transformers and magnetic power compression systems. But this equipment lacks adequate enough energy transfer efficiency and also it is bulky. The authors have reached a pulse voltage of 52 kV for a load of 50 /spl Omega/ with a pulse width of 110 ns (FWHM) for one compression stage. With two stage compressions, they have obtained 70 kV with pulse width of 80 ns (FWHM) for a load of 500 /spl Omega/.
