- Description: Abstract: This paper describes a novel proposal of double quad-inverter configuration for multilevel twelve-phase openwinding ac converter. Modular power units are developed from reconfigured eight classical three-phase voltage source inverters (VSIs). Each VSI has one additional bi-directional switching device (MOSFET/IGBT) per each phase and linked neutral with two capacitors. An original modified single carrier five-level modulation (MSCFM) algorithm is developed and modulates each 2-level VSIs as equivalent to ones 5-level multilevel inverter. Observed set of results are presented with model based numerical simulation software’s (Matlab/PLECS) developments. Further, the results confirm the good agreement to the developed theoretical background. Proposed converter suits the need of low-voltage/high-current applications such as ac tractions and ‘More-Electric Aircraft’ propulsion systems.

- Description: Abstract: This paper developed a novel quad-inverter configuration for multilevel six-phase asymmetrical open-winding AC converter. Proposal found to be suited for (low-voltage/highcurrent) applications such as AC tractions and ‘More-Electric Aircraft’ propulsion systems. Modular power circuit comprises of standard four three-phase voltage source inverter (VSI) and each connected to the open-end windings. Each VSIs are incorporated with one bi-directional switching device (MOSFET/IGBT) per phase and two capacitors with neutral point connected. Further, an original modified single carrier five-level modulation (MSCFM) algorithm is developed in this work and easy for implementing in real digital processors. The proposed modulation algorithm is capable of generating, 5-level voltages at each output of four VSI as one equivalent to multilevel inverter. The total power is among the four DC sources and quadruples the capabilities of VSIs. A set of observed results is presented with numerical software analysis (Matlab/PLECS) in balanced working conditions. Always the results shown good agreement in the developed theoretical background.
