Combined geometrical techniques and applying nonlinear field dependent conductivity layers to address the high electric field stress issue in high voltage high-density wide bandgap power modules

IEEE transactions on dielectrics and electrical insulation, 2020
Wide bandgap (WBG) power modules made from materials such as SiC and GaN (and soon Ga2O3 and diamond), which can tolerate higher voltages and currents than Si-based modules, are the most promising solution for reducing the size and weight of power ...

Experiment of Drying Kelp with High Voltage Electric Fields

2008 International Conference on High Voltage Engineering and Application, 2008
In order to improve the drying qualities of seaweed, a new drying technology with the high voltage electric field was put forward for seaweed in the paper. The kelp were dried under a direct current (DC) high voltage electric field (HVEF) using a multiple point electrode and a grounded rectangle stainless steel plate at 15degC.

Computation of Electric Field Distributions in High-Voltage Equipment

IEEE Transactions on Electrical Insulation, 1971
In an earlier paper two of the authors described a general-purpose digital computer program suitable for solving, with considerable precision, multidielectric fields in two dimensions or in three dimensions with at least one axis of symmetry. The program, after being rigorously checked, has been extensively used for several years to solve many ...

Efficient computation of electric field in high voltage equipment

IEEE Transactions on Magnetics, 1990
The efficient indirect boundary-element method is applied to the calculation of 3-D electric fields in high-voltage devices. For solving this problem with sophisticated boundary conditions and with dielectric media, the authors adopt real surface elements, a fast and accurate computation approach, and thin-layer medium treatment.
