This paper develops a cost-effective and accurate procedure for EMI equivalent model synthesis and validation for a three-level neutral-point-clamped (3L-NPC) inverter. Compared to traditional methods, which require full system measurements or open-module configuration, the proposed method is simpler to implement using double pulse test configurations (with slight circuit modifications). The final paper will cover full scale converter parasitic validation with a three-phase inverter test bed.
