Measurement-Based Method to Characterize Parasitic Parameters of the Integrated Power Electronics Modules

A measurement-based method for extracting the parasitic parameters of active power electronics modules (IPEMs) is proposed. Parasitic inductances and capacitances inside the IPEM can all be extracted using this method without destroying the structure. The linearized model is derived from impedance m...

Description
Summary:A measurement-based method for extracting the parasitic parameters of active power electronics modules (IPEMs) is proposed. Parasitic inductances and capacitances inside the IPEM can all be extracted using this method without destroying the structure. The linearized model is derived from impedance measurement and it is valid from low frequency to frequencies as high as 100 MHz. Extracted parameters are compared to those from commercial software and the results are in good agreement. A parallel resonance method is proposed for the characterization of common-mode capacitances
