Skip to Main Content Three types of resistors have been tested
to determine maximum usable power at pulsed high voltage and
pulsed high current. Experiments were carried out using high
voltage cable generators and spark-gap generators. Pulse
durations were varied from 0.7 /spl mu/s to 21 /spl mu/s. The
pulse amplitudes were varied from 1 kV to 12 kV. The peak
current reached was 3 kA. Metal film, carbon film and carbon
composition resistors of four different rated powers (0.25 W,
0.5 W, 1 W, 2 W) have been tested. Data are given for the
limiting pulsed energy for each type of resistor in nanosecond
and microsecond time ranges. The mechanisms of failure and
destruction of resistors under the action of high voltage and
high current pulses are discussed. Pulsed Power Conference,
