Field analysis and shape optimization for HV potentiometer
Wenxiang Chen, Ya-Zhou Sun, Лалита Удпа · IEEE Transactions on Magnetics · 1999
Finite element analysis of a high-voltage potentiometer used in a television set is presented. The net field is a result of coupling between the current fields and the electric fields. Techniques for optimization using SWIFT nonlinear programming method are developed to solve for shape of the semi-conductive layer in the potentiometer to even out the field strength distributions and reduce the risk of discharge fault.
