MODELING NONLINEAR POWER ELECTRONIC-CIRCUITS WITH THE TRANSMISSION-LINE MODELING TECHNIQUE

This paper describes a non-linear transmission-line modeling technique that can be employed to model power electronic circuits. The non-line arities that can be dealt with include the switching action of the pow er devices as well as the non-linear behavior of saturable inductors a nd multi-layer capacitors. With this new non-linear technique, the tra nsmission-line modeling technique can now be used as a generalized dis crete-time modeling tool for power electronic circuits. The non-linear technique is demonstrated in two examples and the simulations are fou nd to be good.
