Abstract

Metal film type of resistor have been tested to invest maximum usable power at the pulsed high voltage and pulsed high current. Experiments were carried out using capacitor charging power supply and dump switch. Pulsed amplitude were varied from 1kV to 25kV. The peak current reached was 1kA. Datasheet are given for the limited pulsed power and energy for metal film type of resistor in nanosecond and microsecond time range. The experimental investigation of the threshold loading of the resistor in the high current and voltage pulsed mode has shown that the process of destruction of resistor has specific features for each mode. The mechanisms of failure and destruction of resistors under action of high-voltage and high-current pulses are discussed.
