e LS-PWM technique leads to high-quality line voltages since all the carriers are in phase when
compared to other multicarrier PWM methods. In addition since it is based on the output voltage levels
of an inverter, this principle can be easily adapted to any multilevel converter topology. However, this
method is not preferred for CHB and FC, since it causes an uneven power distribution among the dif-
ferent cells. is generates input current distortion in the CHB and a capacitor unbalance in the FC.
14.3.3.2.2  Multicarrier Phase-Shied PWM
Phase-shied PWM (PS-PWM) is a multicarrier PWM method, and is a natural extension of PWM
especially suited to be applied to the FC and CHB [8] converters, mainly ...
