Abstract :
The application of the transmission line modeling (TLM) method to the decoupled simulation of multistage power electronic systems is described. Stiff capacitively or inductively smoothed DC links in power electronic systems can be modeled as two port transmission line links using the TLM method. The TLM links enable the circuits connected by the links to be decoupled and simulated as individual circuits, resulting in smaller system matrices, the possibility of parallel computation, and reduction in computing time. Interaction between these linked circuits can be realized by exchanging the incident pulses at both ends of the transmission line links. Computer simulations of an AC to DC converter used in a teaching laboratory confirm the simplicity of the TLM decoupled simulation approach
