Abstract

The Harmonic Balance Method (HBM) allows an efficient determination of the steady-state solution of mildly non-linear circuits; however, in the presence of strong nonlinearities, it often fails to converge. The reasons of such behavior are investigated in this paper. In order to improve convergence, a modified HEM technique is presented, based upon the idea of filtering used in sampled data systems. This technique has been successfully employed in the simulation of strongly nonlinear circuits, such as periodically switched circuits. Results are reported together with the details of the method
