Abstract

Now-a-days Multilevel inverter are considered the most important and efficient inverter for their better output quality and low voltage stress. quasi-Z Source(q-ZS) converter topology is the extension of Z Source topology in terms of reliability. In this context this paper presents the q-ZSI topology with several levels at the inverter output. A comparative assessment of the improvement of the output voltage is carried out for different levels such as 5-level, 7-level and 9-levl. The series of simulation result followed by a 3rd harmonic distortion (THD) ensures the improvement in case of 9-level.
