Using Double Fourier Series to Analytically Model Common-mode Voltage for Various Modulation Methods in Three-phase Voltage-source Inverters

The past literature, when investigating the common-mode current vs. switching frequency and switching profile, usually evaluated through simulation and experiment while lacking analytical models and tools. Some PWM methods might reduce the common-mode voltage (CMV) at some frequency, however, cause the increasing at other frequency points. Such overall merits and performance between different PWM patterns can only be evaluated by analytical …
