Abstract This paper describes a novel technique with which a system with changing topology can be modelled whilst maintaining a constant system matrix. This technique employs a new transmission‐line switch model which has a constant characteristic impedance, irrespective of its state. The method is explained, compared with the switched‐resistance method and demonstrated by two examples. It has been found that the proposed method offers substantial advantages in the formulation of the problems and in the efficiency of computation.
