To study the dielectric barrier discharges(DBD) using pulsed high voltage,the voltage,the discharge current,and the instantaneous power on the air spacing are calculated according to an equivalent circuit,based on the measured voltage and current in the DBD experiments using positive unipolar nanosecond pulses.

In order to research the apoptosis induction effects of nanosecond pulsed electric field (nsPEF) in vivo,tumor models in 20 female BALB/c nude mice were established by inoculating with human melanoma cells A375.

Because consecutive over-current after dielectric breakdown would damage the power supply,a protective shut-off circuit for repetitive nanosecond-pulse power supply is required.
