m-Mode SVPWM for Multilevel Inverter

2019
Compared with the aforementioned two-level inverter, the multilevel inverter can further reduce the harmonics of the output voltage and current. However, the structure of the multilevel inverter is more complicated, which makes the design of the SVPWM switching sequences more difficult.

A simple SVPWM algorithm for multilevel inverters

2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004
In this paper, a simple space vector pulse width modulation (SVPWM) algorithm for multilevel inverters is proposed. With the proposed method, the three nearest compound vectors can be selected easily and the dwelling time of each vector can be simply calculated for either three-level inverter or inverters with more levels.
