Abstract

This paper focuses on a nine level multilevel inverter with DC link capacitors at the input side. The main disadvantage of cascaded multilevel inverter is the number of DC sources. So a nine level multilevel inverter with DC link switches, which requires less number of DC sources as compared to the conventional multilevel inverter is proposed. Single carrier method is the control strategy used here. A comprehensive literature survey on existing nine level multilevel inverter is carried out. The feasibility of the proposed nine level inverter is verified through simulation. Proposed nine level inverter is compared with the conventional H bridge multilevel inverter.
