A PFN and transmission line simulation method for energy discharge systems

An analysis and simulation algorithm for energy discharge systems consisting of a pulse forming network and a transmission line are discussed. The network formulation is represented in the state space form, and the analysis is based on the network eigensystem. In an energy discharge network, the time response is governed by the system eigenvalues, their weights, and the initial states of the energy storage elements. Therefore, the eigensystem analysis can be applied to simulate the system time response. This method differs from the time difference equation step-iterative simulation in the following aspects: the accuracy of the simulation mainly relies on the eigensystem parameter evaluation; there is no cumulative time step iteration error; the simulation of the network response can be calculated from any moment of time, rather than from the initial time only; and since the method also provides information on the network characteristics, a model reduction can be readily obtained. Some simulation examples are presented
