Automatic Model Generation for PCB-based Power Electronics

This paper describes a workflow which allows to automatically go from the printed circuit board design of a power converter to a circuit model which includes circuit parasitics (a complete ”virtual prototype”). Commercial software (Altium, Ansys Q3D, LTSpice) is used, with custom code at the interfaces. Some systematic simplifications are proposed to accelerate computations. This workflow is demonstrated on an example case and compared to experimental measurements (double pulse waveforms and impedance measurements).
