Abstract

We present a new algorithm to transform any complex system of linear first-order ODEs or second-order undamped ODEs, resulting from the discretization of field PDEs, into 1-D equivalent circuit system. This transformation algorithm offers an extremely simple and convenient way to incorporate field problems in circuit simulators to solve coupled circuit-field problems. We also present a model reduction strategy based on the proposed coordinate transformation algorithm. Numerical example involving a Voltage Regulator Module with MOSFET devices shows a significant reduction of simulation time compared to the solution without using the proposed transformation.
