Best THD of multilevel DC/AC inverters

Multilevel DC/AC inverters have various structures. They have many advantages. Unfortunately, most existing inverters have poor total harmonic distortion (THD) since each level switching angle is not carefully arranged. In order to have good power quality (PQ), we have to carefully investigate the s...

Description
Summary:Multilevel DC/AC inverters have various structures. They have many advantages. Unfortunately, most existing inverters have poor total harmonic distortion (THD) since each level switching angle is not carefully arranged. In order to have good power quality (PQ), we have to carefully investigate the switching angle arrangement to obtain the best THD. The best THD of Multilevel DC/AC Inverters from 3-level to 35-level is derived in this project. No doubt that the best THD Multilevel DC/AC Inverters will draw much attention over the world, and this knowledge will be applied in renewable energy systems, electrical vehicles and other industrial applications.
