Abstract :
A novel approach to time-domain analysis and modelling of power electronic circuits is presented. All circuit components, including active and passive elements, are modeled in a discrete manner by transmission-line sections using the transmission-line modeling (TLM) method. The method requires a fixed system matrix that depends only on the circuit configuration and not on the switching states of the circuit. The circuit transient behavior can be modeled easily. The proposed TLM algorithm, which provides a fast and exact solution to the discrete model, can be programmed easily on a desk-top computer and is stable even for stiff networks
