Modeling non-linear power electronic circuits with the transmission-line modeling technique

This paper describes a nonlinear transmission line modeling technique that can be employed to model power electronic circuits. The nonlinearities that can be dealt with also include the switching action of the power devices as well as the nonlinear behavior of saturable inductors and multilayer capacitors. With this new nonlinear technique, the transmission line modeling technique can now be used as a generalized discrete-time modeling tool for power electronic circuits. The nonlinear technique is demonstrated in two examples and the simulations are found to be satisfactory
