Abstract:This article considers the question of existence and uniqueness of the response of nonlinear time‐varying RLC networks driven by independent voltage and current sources. It is proved that under certain conditions the response exists, is unique, and is defined by a set of ordinary differential equations satisfying some Lipschitz conditions. These conditions are of two types: (1) the network elements must have characteristics which satisfy suitable Lipschitz conditions and (2) the network must satisfy certain to… Show more

SUMMARYFor the class of complete nonlinear RLC-networks the normal form equations can be established by a method given in Brayton and Moser' using the mixed potential. Before applying this approach it is a crucial point to investigate whether a network is complete. To this end in the present paper an algorithm is given which additionally leads to a partitioning of the network under consideration. Two theorems are given enabling the direct construction of the mixed potential starting from the obtained subnetworks. It is shown that complete nonlinear RLC-networks with ideal two-port transformers (RLCT-networks) can be remodelled into complete RLC-networks using a new approach to model non-hybrid transformers. Noncomplete RLCT-networks often can be remodelled into complete RLCTnetworks by inserting additional branches containing controlled sources which d o not affect the mixed potential. Further simplifications are possible using the rules given to derive the so-called 'potential-equivalent' networks which contain less controlled sources but lead to the same normal form equations. Finally some theorems are given concerning the existence and uniqueness of solutions of a cqnplete network where the conditions can be examined directly at the network before establishing the network equations.
“…The history of nonlinear dynamic analyses of transistor circuitry extends back about three decades; some of the early efforts are [1,[4][5][6][7][8][9][20][21][22][23]. Many of those and more recent works concern qualitative properties such as existence, uniqueness, and stability of solutions, although considerable effort has also been expended toward computational problems.…”
