Abstract

The undesired harmonic effects of a three-phase TCR are analyzed in this paper. The basis of a simple model for the description of the dynamic behaviour of a three phase TCR is presented. Two Newton techniques to accelerate the convergence to the limit cycle are described and applied to obtain the periodic steady-state solution of the electric network. The two Newton methodologies and the brute force alternative are compared in terms of total number of cycles and CPU time required to obtain the steady-state solution
