Abstract

The increasing adoption of adjustable speed drives (ASDs) and high-speed power switches has led to electromagnetic interference (EMI) challenges, making accurate EMI modeling essential. This study investigates the measurement of Common Mode (CM) impedance of three-phase induction motors using pulse Frequency Response Analysis (FRA) as an alternative to Vector Network Analyzer (VNA) measurements. The fundamentals of CM impedance measurement using VNAs and pulse FRA are elaborated. The pulse FRA method is implemented with varying pulse frequencies and duty cycles, and its results are compared to VNA measurements over a frequency range of 1 kHz to 30 MHz. The statistical analysis of the results demonstrates that the pulse FRA method can serve as a viable alternative to VNA measurement while maintaining a reasonable level of accuracy.
