Hextuple-inverter configuration for multilevel nine-phase symmetrical open-winding DC converter is articulated in this work. Power modular unit consists of six classical three-phase voltage source inverters (VSI). Each VSI includes one bi-directional device (MOSFET/IGBT) per each phase and link to two capacitors for neutral connection. A modified single carrier five-level modulation (MSCFM) algorithm is developed and modulates each 2-level VSI as 5-level multilevel inverter (MLI). A set of test results is presented, which are observed from the model based developments in numerical simulation software's (Matlab/PLECS). The results always showed good conformity with the developed theoretical background under working conditions. The proposed converter found suited for (low-voltage/high current) electric vehicles, DC tractions and 'More-Electric Aircraft' applications.
