Abstract :
The paper introduces a new FEM technique for considering eddy-currents in multi-conductor windings surrounded by magnetically nonlinear media. Traditional finite element formulation is combined with the so called elimination of inner nodes to achieve fast solution. The effectiveness and “behavior” of the technique was investigated. The presented results are discussed and finally concluded in the paper
