High voltage subnanosecond breakdown

IEEE Transactions on Plasma Science, 1998
Present-day ultra-wideband radiation sources produce Megavolt pulses at hundreds of picosecond (ps) risetimes. Empirical data on the breakdown characteristics for dielectric media at these short time lengths and high voltages are either extremely limited or nonexistent.

LTCC Breakdown Voltage Investigation

Additional Conferences (Device Packaging, HiTEC, HiTEN, and CICMT), 2016
Abstract High voltage properties of the LTCC (Low Temperature Co-Fired Ceramics) cofired ceramic tape are presented. Chauvin Arnoux C.A. 6555 insulation tester is used to measure the leakage current and the resistance. Measurement is possible up to 15 kV. The DuPont 951 test structures are manufactured.

HIGH VOLTAGE BREAKDOWN STUDY

1967
Abstract : The analysis of the results of the preliminary experimental program has been pursued with emphasis on the visible radiation from vacuum gaps. The results are consistent with both thermal and transition radiation phenomena. The 320 kv system has been assembled and the components necessary for the pilot experiment checked out, viz.

Voltage Breakdown in Random Composites

Advanced Engineering Materials, 2003
Voltage breakdown is a strongly localized phenomenon in random‐microstructure composites because the different dielectric constants of metal and polymer matrix turn a uniform external field across the structure into spatially non‐uniform local fields.

Voltage breakdown characteristics of microwave antennas

IRE International Convention Record, 1959
At low pressures, antennas are susceptible to voltage breakdown. In the case of missiles, for example, there are indications that very low power is sufficient to initiate and maintain breakdown. Since it is essential that the system performance is not interrupted for high-altitude operation, an experimental investigation has been made to study the ...

Resistor networks with distributed breakdown voltages

Physical Review A, 1991
As a primitive model for structural breakdown in elastic media, we analyze the failure of random resistor-fuse networks with various distributions of properties. We show that variations in breakdown voltage have a more significant effect than variations in resistance values. This is analogous to the fiuid-displacement problem [D.Y.C. Chan, B. D. Hughes,

Breakdown voltage of high-voltage bipolar transistors

Solid-State Electronics, 1991
Abstract An empirical expression for open-base bulk breakdown voltage of an epitaxial n+pn−n+ bipolar transistor as a function of collector doping density and common-emitter current gain is useful in the design of the collector region of the transistor.

Uncertainty of Soil Breakdown Voltage

2010 International Conference on High Voltage Engineering and Application, 2010
Aim of this work is the analysis of the components of uncertainty and the estimation of the uncertainty regarding the determination of the breakdown voltage associated with the soil critical electric field. For that reason, series of measurements have been conducted by inducing impulse voltages to soil samples with different moisture content in order ...

Avalanche breakdown voltage of In0.53Ga0.47As

Journal of Applied Physics, 2002
Avalanche breakdown voltages were determined for a series of In0.53Ga0.47As p-i-n diodes with i-region thicknesses ranging from 0.4 to 4.79 μm using measurements of reverse dark current and phase-sensitive photomultiplication. Despite its narrower bandgap In0.53Ga0.47As is found to have a very similar breakdown voltage to GaAs.

Effect of Ultraviolet on Breakdown Voltage

Transactions of the American Institute of Electrical Engineers, 1935
The effect of ultraviolet light upon the breakdown voltage of sphere gaps subjected to impulse voltages is considered in this paper. It is shown that, especially for the smaller gaps and corresponding lower voltages, more accurate voltage measurements result when ultraviolet light is used.
