高频三相共模电感特性表征

This letter presents a method to characterize three-phase common-mode chokes at high frequencies. By performing a modal analysis of a high-frequency circuit model of the common mode choke regarded as a six-ports device, we demonstrate that when excited in a simple setup, the common-mode and differential-mode resonances of the three windings of the common mode choke can be plainly observed. This pe...
