| Summary: | The Non-isolated DC Source Symmetric (NDS) multilevel inverter in general features reduced number of power devices requirement when compared to conventional multilevel inverter topologies. It has been designed as such the circuit itself can simply be extended if higher output voltage levels is required. This paper presents an analysis on the DC source lifetime and conduction losses of a single-phase nine-level NDS multilevel inverter. From the analysis conducted, the NDS multilevel inverter has been justified to offer advantages in terms less conduction losses which in turn provides better efficiency and equal life time for each DC source. |
