A Pseudo-Transient Method Using Compound Elements for Finding DC Operating Points

摘要

The pseudo-transient algorithm with the novel compound elements is proposed in this paper, which is regarded as one of the practical methods to achieve a DC operating point solution when the Newton-Raphson method fails in the nonlinear circuit analysis. Examples are demonstrated to prove that, compared with the conventional pseudo-transient algorithms, this algorithm is able to avoid the oscillation problems effectively and improve the simulation efficiency. The mathematical description for the pseudo-transient method is also discussed and analyzed simply.
