Abstract
This paper presents a method to analyze the electric circuit composed of linear subcircuit and nonlinear resistors, inductors capacitors and periodically excited sources. The method uses the generalized power series expansion formulas for nonlinear elements. Harmonic balance type nonlinear equation in the complex frequency domain to determine the steady state response has been obtained by the multinomial expansion theorem up to now. But the process to get the equation is very complicated and cumbersome, so we propose a new method based on the nonlinear steady state response method. This method is suited to the analysis of nonlinear circuit with multi-frequency excitation of arbitrary frequency separation.
Practical computer algorithm is presented and validity of the method is shown by illustrative examples.
