Breakdown threshold of dielectric barrier discharges in ferroelectrets: where Paschen's law fails

open access: yesIEEE Transactions on Dielectrics and Electrical Insulation, 2011
The piezoelectric activity of charged cellular foams (so-called ferroelectrets) is compared against simulations based on a multi-layer electromechanical model and Townsend's model of Paschen breakdown, with the distribution of void heights determined from scanning electron micrographs.

Electric conduction breakdown and partial discharges in dielectric fluids. I. Partial discharges

open access: yes[1991] Proceedings of the 3rd International Conference on Properties and Applications of Dielectric Materials, 2002
Some studies have suggested that there may exist a relationship between conduction and electrical breakdown. Before such a correlation between these phenomena and partial discharges (PDs) can be investigated, it is necessary to produce reproducible PD data.

Susceptibility of dielectric-loaded, vacuum-breakdown discharges in DC

IEEE International Vacuum Electronics Conference, 2014
This 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 ...

Impact of gas flow rate on breakdown of filamentary dielectric barrier discharges

Physics of Plasmas, 2016
The influence of gas flow rate on breakdown properties and stability of pulsed dielectric barrier discharges (DBDs) in a single filament arrangement using a gas mixture of 0.1 vol. % O2 in N2 at atmospheric pressure was investigated by means of electrical and optical diagnostics, accompanied by fluid dynamics and electrostatics simulations.

The breakdown characteristic of porous dielectric discharge based on percolation structure

Plasma Sources Science and Technology, 2023
Abstract 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.

Impact of the electrode proximity on the streamer breakdown and development of pulsed dielectric barrier discharges [PDF]

open access: yesPlasma Sources Science and Technology, 2022
The impact of the electrode proximity on the streamer breakdown and development of pulsed-driven dielectric barrier discharges (DBDs) in a single-filament arrangement has been investigated in a gas mixture of 0.1 vol% O2 in N2 at 0.6 bar and 1.0 bar. The

A stochastic model for dielectric breakdown in thin capacitors

open access: yesJournal of Applied Physics, 1988
A nontrivial two-dimensional stochastic model for dielectric breakdown within a parallel plate capacitor is presented for the first time. The model has been used to determine geometric properties of parallel plate discharges. Comparisons are made between

Charge-discharge breakdown of dielectric ceramic

Proceedings of the 6th International Conference on Properties and Applications of Dielectric Materials (Cat. No.00CH36347), 2002
The breakdown behavior of high-voltage dielectric ceramics experiencing long-time charge and discharge cycles is not the same as its short-time breakdown behavior. In our study, it was found that there are about four types of breakdown and various factors such as test voltage, ceramic Curie temperature, epoxy encapsulation, and interface treatments ...
