Voltage forced coils for 3D finite-element electromagnetic models

Abstract

A method for modeling 3D voltage forced coils is described. The magnetic vector potential A is used within the coil with an additional equation to ensure EMF balance at the terminals. This approach is useful for nonlinear or transient problems when the terminal voltage is specified. The coil model has been incorporated into the general 3D electromagnetics program MEGA. A simple voltage-forced coil has been simulated on the computer and compared with experimental results.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
