Geometry-Based Modeling of EMI of an LCL Filter in an AC-DC-AC Converter with WBG Power Semiconductors

This paper analyzes a grid-side LCL filter's parasitic behavior and gives its parasitic elements sensitivities. It presents a new model for capacitors, improving the accuracy of parasitic inductance predictions. Sensitivity analyses show that the arrangement greatly influences the filter's performance and electromagnetic behavior, even in the low-frequency range.
