What is a common mode signal in a 3 phase inverter?
The common mode signal is made up of third harmonics of the supply frequency (called "triplens"). Since the same common mode signal is added to all three phases, the line-line output will not contain the common mode signal. Consider first the 3-phase inverter shown below (figure 2)
