The breakdown characteristic of porous dielectric discharge based on percolation structure
Plasma Sources Science and Technology, 2023Abstract Porous dielectrics have received increasing attention in plasma sterilization, all-solid-state battery technology, and surface functionalization of biological tissue materials. Due to their complex structure and discharge characteristics, the current researches are hard to quantify the stochastic properties of porous dielectrics.

Breakdown characteristics in dielectric-confined microcavity discharge of plate electrodes
Journal of Physics D: Applied Physics, 2023Abstract Breakdown characteristics in dielectric-confined microcavity discharge of plate-to-plate electrodes under DC voltage are investigated in this paper. Experimental and particle-in-cell/Monte Carlo code simulated results show that the breakdown characteristic curve (the relation between the breakdown voltage V br ...

Susceptibility of dielectric-loaded, vacuum-breakdown discharges in DC
IEEE International Vacuum Electronics Conference, 2014This work presents a novel, simplified theory of breakdown susceptibility in dielectric-loaded systems operating in DC, with multipactor targeted as the effect of lowest-order. Limits for susceptibility are drawn with the well-known characteristics of secondary-emission [1], and 2-D particle-in-cell modeling is used to monitor the evolution of ...

Dielectric breakdown and discharge energy on printed circuit board
Proceedings of the 2004 IEEE International Conference on Solid Dielectrics, 2004. ICSD 2004., 2004An investigation of the influences of the environmental factors on breakdown strengths, discharge energy, density of electric field associated with discharge occurring on surface printed circuit board were discussed. The PD characteristics and phenomena in an air cavity on the printed circuit board were also discussed. The environmental factors include

Simulation of breakdown in dielectric barrier discharges at atmospheric pressure
Journal of Physics D: Applied Physics, 2004Breakdown at atmospheric pressure in a nitrogen discharge is examined using analytic calculations and numerical solutions of the fluid equations and the Boltzmann equation. The fully analytic capacitor model is set up by dividing the discharge 'capacitor' into N small capacitors and letting them break down one at a time.

2018 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), 2018
Dielectric polymers which can operate at high temperature (> 150 °C) and high electric fields with high performance such as high charge/discharge efficiency and dielectric strength are required for many capacitor applications including energy storage and electric insulators.

Aspects of dielectric breakdown preceded by discharges
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1974, 1974The point-plane gap has been widely used in studies of discharges and breakdowns of gases, liquids and solids (the last including treeing tests). For this geometry, the ratio of maximum to average electric stress is calculable from E max /E av = 2d/[r ln(1 + 4d/r)] (1) where r is the point radius and d is the distance of point to plane.

Some aspects of the breakdown of dielectric fluids by internal discharges
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1969, 1969Ionization under high electric stresses may occur in voids located in liquid hydrocarbon impregnated paper or plastic tape composite dielectrics, with evolution of hydrocarbons. If these active (or nascent) gaseous breakdown products are not swiftly re-absorbed, the degradation site may grow and the process become self-accelerating to destruction ...

Investigation of Discharge Channel Elongation under Thermal Dielectric Breakdown
Russian Physics Journal, 2003A mathematical model of the expansion of a discharge channel due to a growing electrothermal instability in a solid dielectric material under constant voltage is considered. The model describes temperature dynamics, electric field strength, discharge density, and melting of the dielectric.

Study on the breakdown process in dielectric barrier discharge with a magnetohydrodynamic method
Physica Scripta, 1996With the magnetohydrodynamic method, the breakdown process in a microdischarge of the Dielectric Barrier Discharge is analyzed. A theoretical model is established to simulate a microdischarge on the basis of the properties of the microdischarge and the effect of the dielectric.
