A Novel Multilevel Inverter Topology Producing 9-Level to 17-Level Voltage with Reduced Switch Count

This paper presents a novel single-phase multilevel inverter with capability of developing 9, 11, 13, 15, and 17-levels in its output voltage. The proposed inverter is able to develop the multilevel output voltage with the help of symmetric as well as asymmetric dc-link voltage sources. The proposed multilevel inverter develops different voltage levels with reduced switch count compared to other presented topologies of multilevel inverters. Along with the reduced switch count the said multilevel inverter has the advantage of reduced blocking voltage requirement of switches and also less number of dc-link sources. Steady-state as well as a transient performance of the proposed multilevel inverter is analysed by simulation study using MATLAB. Satisfactory performance of the proposed multilevel inverter is demonstrated.
