Abstract :
In this paper a SPICE-compatible distributed circuit modelling method is applied to the modelling of printed circuit boards (PCBs) typically found in a DC-DC converter design. The method consists of identifying each pair of parallel plates present in a PCB and modelling it by a two-dimensional array of lossy transmission line elements. The impedance profile of the PCB is simulated in SPICE. The simulation results of the distributed circuit model are validated by comparing them to the simulation results obtained from a commercial electromagnetic (EM) solver. The presented method enables a fast and numerically efficient design, analysis and optimization of PCBs for DC-DC converters.
