NEW ALGORITHM AND PROGRAM FOR NONLINEAR DYNAMIC CIRCUITS SIMULATION

摘要

The objective of this paper is to present a new algorithm, his associated program too, dedicated on the simulation and analysis of the nonlinear dynamic circuits. The analysed circuit may contain any type of independent or coupled lumped circuit elements, any type of excess elements; there are no restrictions on network topology. The proposed algorithm is based on the time-domain generalized nodal analysis; a connexion is established between the "classic" modified nodal analysis and the state-variable approach. An example is given, illustrating the automatically generation of the circuit equations, in their symbolic form, by the implemented algorithm; the built program solve the differential-algebraic equations (DAE) formerly formulated.
